TPS65132L Evaluation Module
5 Setup
5.1 Hardware Connections
Figure 2 shows how to connect the EVM to a dc power supply, a load, and a host PC.

Figure 2. Hardware Setup – Full Functionality
If no changes to the output voltages or to any other configuration settings are needed, use the simplified
set-up shown in
Figure 3 . If using the simplified setup, the TPS65132L device starts up with the register
settings stored in its EEPROM the last time it was programmed.

Use two-terminal ( Figure 4 ) or four-terminal ( Figure 5 ) connections to connect the power supply to the
EVM. Two-terminal connections are simpler, but four terminal connections are more accurate.
To minimize parasitic inductance, TI recommends using a short cable (less than 20 cm) and twist the
power (VIN) and return (GND) conductors together.
