TPS65381A-Q1: Multiple use

user5093781

Part Number: TPS65381A-Q1
Hi. For example, suppose there are two TMS570s on one board and each has a TPS65381A connected. I want to supply the VDD3 of the TPS65381A to ICs other than the TMS570, but because of insufficient current capacity, can I make a connection that also supplies the second TPS65381A? Does the TPS65381A supply power to one IC? Please provide information if you have such an example. Best regards.

Hi,

Unfortunately we don't have an example or application note that matches your use case.

However, I am curious if you are already using VSOUT1 output in your design? If not, you could configure VSOUT1 to operate at 3.3V and have an additional 100 mA from each of the TPS65381A-Q1 devices on your board.

Regards,
Ivan
