2.1.5 Configuring EVM to Overdrive VDRV
The EVM has a terminal connection J4 that is used to overdrive the VDRV. The output of the internal regulator is
set for 4.5V by default. Using the external supply is useful to minimize the power dissipation in the TPS546C25
IC when operating at high switching frequency. Overdriving the VDRV moves the loss from the internal regulator
of the TPS546C25 to the external supply. To use the external supply, follow the steps on the EVM as follows:
1. Connect external supply to J4 and set external supply to between 4.5V to 5.5V.
2. Power up the external supply to overdrive VDRV, then power up PVIN .
