description

The TPS6030x step-up, regulated charge pumpsgenerate a 3-V 4% or 3.3-V 4% output voltage

from a 0.9-V to 1.8-V input voltage (one alkaline,NiCd, or NiMH battery).

Only five small 1-F ceramic capacitors are required to build a complete high efficiency dc/dc charge pumpconverter. To achieve the high efficiency over a wide input voltage range, the charge pump automatically selectsbetween a 3x or 4x conversion mode.

detailed description

operating principle

The TPS6030x charge pumps are voltage quadruplers that provide a regulated 3.3-V or 3.0-V output from a

0.9-V to 1.8-V input. They deliver a maximum load current of 20 mA. Designed specifically for space criticalbattery powered applications, the complete converter requires only five external capacitors and enables the

design to use low-cost, small-sized, 1-F ceramic capacitors. The TPS6030x circuits consist of an oscillator,a voltage reference, an internal resistive feedback circuit, an error amplifier, two charge pump stages withMOSFET switches, a shutdown/start-up circuit, and a control circuit.

shutdown

Driving EN low disables the converter. This disables all internal circuits, reducing input current to only 0.05 A.Leakage current drawn from the output pins OUT1 and OUT2 is a maximum of 1 A. The device exits shutdownonce EN is set high (see start-up procedure described below). The typical no-load, start-up time is 400s. Whenthe device is disabled, the load is isolated from the input. This is an important feature in battery operated

products because it extends the battery shelf life.

start-up procedure

The device is enabled when EN is set from logic low to logic high. CP1 will first enter a dc start-up mode during

which the capacitor on OUT1 is charged up to about VIN. After that, it starts switching to boost the voltage furtherup to about two times VIN. CP2 will then follow and charge up the capacitor on OUT2 to about the voltage onOUT1, after that, it will also start switching and boost up the voltage to its nominal value. EN must not exceedthe highest voltage applied to the device.

NOTE:

During start-up with VOUT= 0 V, the highest voltage is the input voltage.

power-good detector

The power-good output is an open-drain output on the TPS60300 and TPS60301 or a push-pull output on theTPS60302 and TPS60303. The PG-output pulls low when the output of OUT2 is out of regulation. When theoutput rises to within 98% of regulation, the power-good output goes active high. In shutdown, power-good ispulled low. In normal operation, an external pullup resistor with the TPS60300 and TPS60301 is typically used

to connect the PG pin to VOUT. The resistor should be in the 100-kto 1-Mrange. If the PG output is not used,it should remain unconnected. Output current at PG (TPS60302, TPS60303) will reduce maximum outputcurrent at OUT2.

APPLICATION INFORMATION

design procedure

capacitor selection

The TPS6030x devices require only five external capacitors. Their values are closely linked to the requiredoutput current and the output noise and ripple requirements. It is possible to only use 1-F capacitors of thesame type.

The input capacitor improves system efficiency by reducing the input impedance and stabilizing the inputcurrent.

The minimum required capacitance of the output capacitor (CO) that can be selected is 1 F. Depending on themaximum allowed output ripple voltage, larger values can be chosen. Table 1 shows capacitor valuesrecommended for low output voltage ripple operation. A recommendation is given for the smallest size.

Figure 20. Typical Operating Circuit

For the maximum output current and best performance, five ceramic capacitors of 1 F are recommended. For

lower currents or higher allowed output voltage ripple, other capacitors can be used.It is recommended that theinput and output capacitors have a minimum value of 1F. This value is necessary to assure a stable operationof the system due to the linear mode. With flying capacitors lower than 1 F, the maximum output power willdecrease. This means that the device will work in the linear mode with lower output currents.

output filter design

The power-good output is capable of driving light loads up to 5 mA (see Figure 21). Therefore, the outputresistance of the power-good pin, in addition with an output capacitor, can be used as an RC-filter.

design procedure (continued)

Due to R(PG,1), an output filter can easily be formed with an output capacitor (CPG). Cut-off frequency is givenby:

V(PG,1)V

O(OUT2)

0.175Load current sourced by power-good output reduces maximum output current at OUT2. During start-up (powergood going high) current charging C(PG)will discharge C(OUT2). Therefore, C(PG)must not be larger than 0.1C(OUT2)or the device will not start. By charging C(PG)through C(OUT2),the output voltage at OUT2 will decrease.If the capacitance of C(PG)is to large, the circuit will detect power bad. The power-good output will go low anddischarge C(PG). Then the cycle starts again. Figure 22 shows a configuration with an LC-post filter to furtherreduce output ripple and noise.

power dissipation

As given in the data sheet, the thermal resistance of the unsoldered package is RJA= 294C/W. Soldered onthe EVM, a typical thermal resistance of RJA(EVM)= 200C/W was measured.

The thermal resistance can be calculated as follows:

RJA

T

JT

A

PD

Where:

TJis the junction temperature.TAis the ambient temperature.PDis the power that needs to be dissipated by the device.

The maximum power dissipation can be calculated with the following formula:

PD= VINIINVOIO= VIN(max)(3 IO+ I(SUPPLY))VOIO

The maximum power dissipation happens with maximum input voltage and maximum output current:

At maximum load the supply current is approximately 2 mA.

PD= 1.8 V (3 20 mA + 2 mA)3.3 V 20 mA = 46 mW.

With this maximum rating and the thermal resistance of the device on the EVM, the maximum temperature riseabove ambient temperature can be calculated:

TJ= RJAPD= 200C/W 46 mW = 10C

This means that internal dissipation increases TJby 10C.

The junction temperature of the device must not exceed 125C.

This means the IC can easily be used at ambient temperatures up to:

TA= TJ(max)TJ= 125C10C = 115C

layout and board space

All capacitors should be soldered as close as possible to the IC. A PCB layout proposal for a two-layer boardis shown in Figure 24. Care has been taken to connect all capacitors as close as possible to the circuit to achieveoptimized output voltage ripple performance. The bottom layer is not shown in Figure 24. It only consists of aground-plane with a single track between the two viasthat can be seen in the left part of the top layer.
