TPS2543-Q1: Vin drops a very short time period

Frank QIN

Part Number: TPS2543-Q1

Hi Team,

If the Vin of TPS2543-Q1 drops below UVLO in 1ms, and then recover immediately. How long will the 5V output be pulled down? Do we have such test results?

Hi Frank,

If VIN drop below UVLO, VOUT drops immediately with assumption that attached heavy load.

As turn on, still need 2.7ms turn on time. It's around 3.7ms.
