Richard Haats

Part Number: TPS53353

Hello,

I would like to know what happens to the TPS53353 under the below two conditions: The TPS5353 is configured as Auto Skip mode.

Case 1: PGOOD always grounded

Case 2: PGOOD always floating

Thank You

Richard,
The PGOOD is an open drain output. If you do not want to use that function, it is perfectly acceptable to leave it open. I cannot think of any way to damage the TPS53353 by connecting the PGOOD pin to GND,
