SLUUCQ1 March 2023 TPS546D24S
The EVM has an external LDO (U2) that can be used to overdrive VDD5. The output of this LDO is set for 5.1 V by default. This LDO is useful to minimize the power dissipation in the TPS546D24S IC when using a single rail input. Overdriving VDD5 moves the loss from the internal LDO of the TPS546D24S to the external LDO (U2). To use this LDO, configure the jumpers on the EVM as follows:
