Introduction
IntroductionThe MxL7204 evaluation board provides a platform to evaluate the features and performance of the MxL7204. The MxL7204 is a dual 4A Power Module optimized for powering Telecom, Networking and Industrial equipment.
The factory default configuration for the MxL7204 Evaluation Board is
■ VOUT1 = 3.3V ■ VOUT2 = 1.8V ■ 780kHz switching frequency
Please refer to the MxL7204 datasheet for additional information about the MxL7204, including efficiency curves for this configuration with VIN = 12V.

Evaluation Board OverviewThe block diagram shown in Figure 2 illustrates the connection points for VIN, VOUT1, VOUT2, TRACK, MODE and RUN pins.
Ordering Information / Overview
System Set-UpJumpers are factory installed per Table 2 to configure the EVB for operation. Jumper and testing options are described in the next sections. Refer to the product data sheet for additional information.
Table 2: Factory Settings
Jumper Factory Setting DescriptionJ_MODE Jumper 1-3 Mode_PLLIN = GND, forced Continuous Conduction Mode (CCM)
J_TRACK1 Jumper 2-3 TRACK/SS1 = GND, Soft-Start mode

Powering Up the Evaluation Board■ Connect the VIN+/VIN- with short, thick leads to a 5.5V to 20V (12V typical) power supply. Use
test pins VIN and GND to monitor VIN and GND respectively. See Note A.■ Turn on the power supply. The MxL7204 EVB will power up and regulate the channel 1 output at
3.3V and channel 2 output at 1.8V.

Monitoring or Testing VOUT■ For the channel 1 output, connect VOUT1+/VOUT1- with short, thick leads to an electronic load
or DUT. Use test pins VOUT1 and GND9 to monitor VOUT1+ and VOUT1- respectively. SeeNote B.
■ For the channel 2 output, connect VOUT2+/VOUT2- with short, thick leads to an electronic loador DUT. Use test pins VOUT2 and GND8 to monitor VOUT2+ and VOUT2- respectively. SeeNote C.

If there is no jumper or if the jumper is set to the PS position with the jumper connected between EXT_CLK and PS (1-2), and with MODE_PLLIN floating (no jumper) or connected to INTVCC (1-2), both channels are forced into pulse-skipping mode of operation.
An external clock supply may be applied to MODE_PLLIN pin. To do this, first remove the J_MODE jumper and connect the external clock to EXT_CLK. This will force both channels into continuous mode of operation.
Jumper J_MODEBy default, the jumper is set in CCM position (2-3) with the jumper connected between EXT_CLK and CCM. In this configuration, connect MODE_PLLIN pin to SGND which forces both channels into forced continuous mode of operation. The MxL7204 EVB will operate in “forced CCM”.

Figure 5: Jumper J_MODE
Header EXTVCCAn external power input may be applied to EXTVCC. It is enabled into the MxL7204 through an internal switch in the IC to drive INTVCC whenever EXTVCC is greater than 4.7V. Do not exceed 6V on the EXTVCC input. Connect the EXTVCC pin to VIN when VIN is less than 5.5V. Note from the datasheet that VIN must be applied before EXTVCC and EXTVCC must be removed before VIN.

Jumper J_TRACK1By default, the jumper is set in the SOFT-START position with TRACK1 pin connect to GND (2-3). Refer to pin description the product datasheet for other options. Changing the jumper to (1-2) connects the TRACK1 pin for output voltage tracking.
Jumper J_TRACK2By default, the jumper is set in the SOFT-START position with TRACK2 pin connect to GND (5-6). Refer to the pin description of the product datasheet for other options. Note that the jumper can be changed to 3-4 for TRACK (using R15 and R18 on bottom side) or 1-2 (using R10 and R13 on bottom side) to change the resistor values for TRACK. These resistors can be populated as desired. See the schematic as an example where R15 = R18 = 60.4kΩ.

Jumpers J_RUN1 and J_RUN2If desired, putting a jumper on headers J_RUN1 or J_RUN2 will inhibit their respective outputs, VOUT1 or VOUT2. Without a jumper on the respective J_RUN header, the output will not be inhibited.
PGOODThe Power Good output can be monitored. Also there is another point, PGOOD_PULLUP, where a different pullup voltage can be applied to alter the PGOOD high level voltage.
