DescriptionThe second generation CoolSET™-F2 provides severalspecial enhancements to satisfy the needs for low powerstandby and protection features. In standby modefrequency reduction is used to lower the powerconsumption and support a stable output voltage in thismode. The frequency reduction is limited to 20kHz/21.5kHz to avoid audible noise. In case of failure modes likeopen loop, overvoltage or overload due to short circuit thedevice switches in Auto Restart Mode which is controlled bythe internal protection unit. By means of the internal precise

peak current limitation the dimension of the transformer andthe secondary diode can be lower which leads to more costefficiency.

Figure 3 Pin Configuration (top view)

1.4 Pin Functionality

SoftS (Soft Start & Auto Restart Control)

This pin combines the function of Soft Start in case ofStart Up and Auto Restart Mode and the controlling ofthe Auto Restart Mode in case of an error detection.

FB (Feedback)

The information about the regulation is provided by theFB Pin to the internal Protection Unit and to the internalPWM-Comparator to control the duty cycle.

Isense (Current Sense)

The Current Sense pin senses the voltage developedon the series resistor inserted in the source of theintegrated CoolMOS™. When Isense reaches theinternal threshold of the Current Limit Comparator, theDriver output is disabled. By this means the OverCurrent Detection is realized.

Furthermore the current information is provided for thePWM-Comparator to realize the Current Mode.

Drain (Drain of integrated CoolMOS™)

Pin Drain is the connection to the Drain of the internalCoolMOSTM.

VCC (Power supply)

This pin is the positiv supply of the IC. The operatingrange is between 8.5V and 21V.

To provide overvoltage protection the driver getsdisabled when the voltage becomes higher than 16.5Vduring Start Up Phase.

GND (Ground)

This pin is the ground of the primary side of the SMPS.

Functional Description

3 Functional Description3.1 Power Management

Figure 5 Power Management

The Undervoltage Lockout monitors the externalsupply voltage VVCC. In case the IC is inactive thecurrent consumption is max. 55µA. When the SMPS isplugged to the main line the current through RStart-up

charges the external Capacitor CVCC. When VVCC

exceeds the on-threshold VCCon=13.5V the internal biascircuit and the voltage reference are switched on. Afterthat the internal bandgap generates a referencevoltage VREF=6.5V to supply the internal circuits. Toavoid uncontrolled ringing at switch-on a hysteresis isimplemented which means that switch-off is only afteractive mode when Vcc falls below 8.5V.

In case of switch-on a Power Up Reset is done byreseting the internal error-latch in the protection unit.

When VVCC falls below the off-threshold VCCoff=8.5V theinternal reference is switched off and the Power Downreset let T1 discharging the soft-start capacitor CSoft-Start

at pin SoftS. Thus it is ensured that at every switch-onthe voltage ramp at pin SoftS starts at zero.

3.2 Improved Current Mode

Figure 6 Current Mode

Current Mode means that the duty cycle is controlled

by the slope of the primary current. This is done bycomparison the FB signal with the amplified currentsense signal.

Figure 7 Pulse Width Modulation

In case the amplified current sense signal exceeds theFB signal the on-time Ton of the driver is finished byreseting the PWM-Latch (see Figure 7).

CoolSET™-F2

Functional Description

The primary current is sensed by the external seriesresistor RSense inserted in the source of the integratedCoolMOS™. By means of Current Mode the regulation

of the secondary voltage is insensitive on linevariations. Line variation causes varition of theincreasing current slope which controls the duty cycle.

The external RSense allows an individual adjustment ofthe maximum source current of the integratedCoolMOS™.

Figure 8 Improved Current Mode

To improve the Current Mode during light loadconditions the amplified current ramp of the PWM-OPis superimposed on a voltage ramp, which is built bythe switch T2, the voltage source V1 and the 1st orderlow pass filter composed of R1 and C1(see Figure 8,Figure 9). Every time the oscillator shuts down for max.duty cycle limitation the switch T2 is closed by VOSC.

When the oscillator triggers the Gate Driver T2 isopened so that the voltage ramp can start.

In case of light load the amplified current ramp is tosmall to ensure a stable regulation. In that case theVoltage Ramp is a well defined signal for thecomparison with the FB-signal. The duty cycle is thencontrolled by the slope of the Voltage Ramp.

By means of the Comparator C5, the Gate Driver isswitched-off until the voltage ramp exceeds 0.3V. Itallows the duty cycle to be reduced continously till 0%by decreasing VFB below that threshold.

Figure 9 Light Load Conditions

3.2.1 PWM-OP

The input of the PWM-OP is applied over the internalleading edge blanking to the external sense resistorRSense connected to pin ISense. RSense converts thesource current into a sense voltage. The sense voltageis amplified with a gain of 3.65 by PWM OP. The outputof the PWM-OP is connected to the voltage source V1.The voltage ramp with the superimposed amplifiedcurrent singal is fed into the positive inputs of the PWM-Comparator, C5 and the Soft-Start-Comparator.

3.2.2 PWM-ComparatorThe PWM-Comparator compares the sensed currentsignal of the integrated CoolMOSTM with the feedbacksignal VFB (see Figure 10). VFB is created by anexternal optocoupler or external transistor incombination with the internal pullup resistor RFB andprovides the load information of the feedback circuitry.When the amplified current signal of the integratedCoolMOS™ exceeds the signal VFB the PWM-Comparator switches off the Gate Driver.

Functional Description

3.3 Soft-Start

Figure 11 Soft-Start Phase

The Soft-Start is realized by the internal pullup resistorRSoft-Start and the external Capacitor CSoft-Start (seeFigure 2). The Soft-Start voltage VSoftS is generated bycharging the e ternal capacitor C b the internal

pullup resistor RSoft-Start. The Soft-Start-Comparatorcompares the voltage at pin SoftS at the negative inputwith the ramp signal of the PWM-OP at the positive

input. When Soft-Start voltage VSoftS is less thanFeedback voltage VFB the Soft-Start-Comparator limitsthe pulse width by reseting the PWM-Latch (see Figure11). In addition to Start-Up, Soft-Start is also activatedat each restart attempt during Auto Restart. By meansof the above mentioned CSoft-Start the Soft-Start can bedefined by the user. The Soft-Start is finished whenVSoftS exceeds 5.3V. At that time the Protection Unit isactivated by Comparator C4 and senses the FB byComparator C3 wether the voltage is below 4.8V whichmeans that the voltage on the secondary side of theSMPS is settled. The internal Zener Diode at SoftS withbreaktrough voltage of 5.6V is to prevent the internal

circuit from saturation (see Figure 12).

Figure 12 Activation of Protection Unit

The Start-Up time TStart-Up within the converter outputvoltage VOUT is settled must be shorter than the Soft-Start Phase TSoft-Start (see Figure 13).

By means of Soft-Start there is an effectiveminimization of current and voltage stresses on theintegrated CoolMOS™, the clamp circuit and the outputovershoot and prevents saturation of the transformerduring Start-Up.

The oscillator generates a frequency fswitch = 67kHz/ 100kHz. A resistor, a capacitor and a current sourceand current sink which determine the frequency areintegrated. The charging and discharging current of theimplemented oscillator capacitor are internallytrimmed, in order to achieve a very accurate switchingfrequency. The ratio of controlled charge to discharge

current is adjusted to reach a max. duty cycle limitationof Dmax=0.72.

3.4.2 Frequency Reduction

The frequency of the oscillator is depending on thevoltage at pin FB. The dependence is shown in Figure14. This feature allows a power supply to operate atlower frequency at light loads thus lowering theswitching losses while maintaining good crossregulation performance and low output ripple. In caseof low power the power consumption of the wholeSMPS can now be reduced very effective. The minimal

reachable frequency is limited to 20kHz/21.5 kHz toavoid audible noise in any case.

Figure 14 Frequency Dependence

3.5 Current Limiting

There is a cycle by cycle current limiting realised by theCurrent-Limit Comparator to provide an overcurrentdetection. The source current of the integratedCoolMOSTM is sensed via an external sense resistorRSense . By means of RSense the source current istransformed to a sense voltage VSense. When thevoltage VSense exceeds the internal threshold voltageVcsth the Current-Limit-Comparator immediately turnsoff the gate drive. To prevent the Current Limiting from

distortions caused by leading edge spikes a LeadingEdge Blanking is integrated at the Current Sense.Furthermore a Propagation Delay Compensation isadded to support the immedeate shut down of theCoolMOS™ in case of overcurrent.

3.5.1 Leading Edge Blanking

Figure 15 Leading Edge Blanking

Each time when CoolMOS™ is switched on a leadingspike is generated due to the primary-sidecapacitances and secondary-side rectifier reverserecovery time. To avoid a premature termination of theswitching pulse this spike is blanked out with a timeconstant of tLEB = 220ns. During that time the output of

CoolSET™-F2

Functional Description

the Current-Limit Comparator cannot switch off thegate drive.

3.5.2 Propagation Delay Compensation

In case of overcurrent detection by ILimit the shut downof CoolMOS™ is delayed due to the propagation delayof the circuit. This delay causes an overshoot of thepeak current Ipeak which depends on the ratio of dI/dt ofthe peak current (see Figure 16).

.

Figure 16 Current Limiting

The overshoot of Signal2 is bigger than of Signal1 due

to the steeper rising waveform.A propagation delay compensation is integrated tobound the overshoot dependent on dI/dt of the risingprimary current. That means the propagation delaytime between exceeding the current sense thresholdVcsth and the switch off of CoolMOS™ is compensatedover temperature within a range of at least.

So current limiting is now capable in a very accurateway (see Figure 18).

The propagation delay compensation is done bymeans of a dynamic threshold voltage Vcsth (see Figure17). In case of a steeper slope the switch off of the

driver is earlier to compensate the delay.

E.g. Ipeak = 0.5A with RSense = 2 . Without propagationdelay compensation the current sense threshold is setto a static voltage level Vcsth=1V. A current ramp ofdI/dt = 0.4A/µs, that means dVSense /dt = 0.8V/µs, and apropagation delay time of i.e. tPropagation Delay =180nsleads then to a Ipeak overshoot of 12%. By means ofpropagation delay compensation the overshoot is onlyabout 2% (see Figure 18).

Figure 18 Overcurrent Shutdown

3.6 PWM-Latch

The oscillator clock output applies a set pulse to thePWM-Latch when initiating CoolMOS™ conduction.After setting the PWM-Latch can be reset by the PWM-OP, the Soft-Start-Comparator, the Current-Limit-Comparator, Comparator C3 or the Error-Latch of theProtection Unit. In case of reseting the driver is shutdown immediately.

3.7 Driver

The driver-stage drives the gate of the CoolMOS™and is optimized to minimize EMI and to provide highcircuit efficiency. This is done by reducing the switch onslope when reaching the CoolMOS™ threshold. This isachieved by a slope control of the rising edge at thedriver’s output (see Figure 19).

Thus the leading switch on spike is minimized. WhenCoolMOS™ is switched off, the falling shape of thedriver is slowed down when reaching 2V to prevent anovershoot below ground. Furthermore the driver circuit

is designed to eliminate cross conduction of the outputstage. At voltages below the undervoltage lockoutthreshold VVCCoff the gate drive is active low.

Functional Description

3.8 Protection Unit (Auto Restart Mode)

An overload, open loop and overvoltage detection isintegrated within the Protection Unit. These threefailure modes are latched by an Error-Latch. Additionalthermal shutdown is latched by the Error-Latch. In caseof those failure modes the Error-Latch is set after ablanking time of 5µs and the CoolMOS™ is shut down.That blanking prevents the Error-Latch from distortionscaused by spikes during operation mode.

3.8.1 Overload / Open Loop with Normal

Load

Figure 20 shows the Auto Restart Mode in case ofoverload or open loop with normal load. The detectionof open loop or overload is provided by the ComparatorC3, C4 and the AND-gate G2 (see Figure 21). Thedetection is activated by C4 when the voltage at pinSoftS exceeds 5.3V. Till this time the IC operates in theSoft-Start Phase. After this phase the comparator C3can set the Error-Latch in case of open loop or overloadwhich leads the feedback voltage VFB to exceed thethreshold of 4.8V. After latching VCC decreases till8.5V and inactivates the IC. At this time the externalSoft-Start capacitor is discharged by the internal

transistor T1 due to Power Down Reset. When the ICis inactive VVCC increases till VCCon = 13.5V by chargingthe Capacitor CVCC by means of the Start-Up ResistorRStart-Up. Then the Error-Latch is reset by Power UpReset and the external Soft-Start capacitor CSoft-Start ischarged by the internal pullup resistor RSoft-Start . Duringthe Soft-Start Phase which ends when the voltage atpin SoftS exceeds 5.3V the detection of overload andopen loop by C3 and G2 is inactive. In this way the StartUp Phase is not detected as an overload.

Functional Description

But the Soft-Start Phase must be finished within theStart Up Phase to force the voltage at pin FB below thefailure detection threshold of 4.8V.

3.8.2 Overvoltage due to Open Loop with

No Load

Figure 22 Auto Restart Mode

Figure 22 shows the Auto Restart Mode for open loopand no load condition. In case of this failure mode theconverter output voltage increases and also VCC. Anadditional protection by the comparators C1, C2 andthe AND-gate G1 is implemented to consider thisfailure mode (see Figure 23).The overvoltage detectionis provided by Comparator C1 only in the first timeduring the Soft-Start Phase till the Soft-Start voltageexceeds the threshold of the Comparator C2 at 4.0Vand the voltage at pin FB is above 4.8V. When VCCexceeds 16.5V during the overvoltage detection phaseC1 can set the Error-Latch and the Burst Phase duringAuto Restart Mode is finished earlier. In that caseT is shorter than T By means of C2 the

normal operation mode is prevented from overvoltagedetection due to varying of VCC concerning theregulation of the converter output. When the voltage

VSoftS is above 4.0V the overvoltage detection by C1 isdeactivated.

Figure 23 Overvoltage Detection

3.8.3 Thermal Shut Down

Thermal Shut Down is latched by the Error-Latch when junction temperature T j of the pwm controller isexceeding an internal threshold of 140°C. In that casethe IC switches in Auto Restart Mode.
