TPS54418A: Design clarification : PWRGD pin

NIKHITHA ANTONY

Part Number: TPS54418A
Other Parts Discussed in Thread: TPS62827A, TPS62865

We are using TPS54418A as buck in one of our design. We are not planning to use Power good output. So can we provide No connect for PWRGD pin of IC TPS54418A.

Kindly let me know

Hi,

Yes, you can leave PWRGD floating if you are not using it.

I would also recommend the newer, smaller, cheaper TPS62827A or TPS62865 instead.

Thanks,

Chris
