Part Number: TPS62140A

Hello team ,

I'm trying to use TPS62140ARGTR in my design. Could you please help to review schematic attached herewith. Though I have checked with Webench design , still if any feedback from past experience will help.

The schematics look fine. The soft start cap values are quite low especially the 1.2V design and you might want to increase this else during startup you might observe device run into current limit.

Thanks,

Amod

Hello Amod,

Will 1uF solve inrush issue ?

You can try using a 3300pF soft start cap (C31 and C32)

Thanks,
