Part Number: TPS65381A-Q1
Other Parts Discussed in Thread: TMS570LC4357,Hello. I use TMS570LC4357, andI am considering power supply to TPS65381A. Can the power supply of the TMS570LC4357 be guaranteed with the TPS65381A? Looking at the ICC maximum value in the data sheet of TMS570, I think it is not enough. Should I create a separate core power supply? Best regards.

Hi,

For TMS570LC4357 MCU, we recommend using the TPS65381A-Q1 + a downstream DCDC converter (such as the TPS57112-Q1) supplied by the VDD6 pre-regulator of the TPS65381A-Q1. Please refer to the following post which discusses this configuration in detail.

Best regards,
