TPS62160-Q1: Slew Limitation on VIN pin

Jared Becker

Part Number: TPS62160-Q1

Hi Team,

Is there any slew rate limitation on the TPS62160-Q1 VIN pin? There is another DC/DC converter that feeds the TPS62160-Q1 with a very fast turn-on, and I want to make sure that will not impact the TPS62160-Q1 VIN..

Thank you!

Jared,

What is the slew rate at which VIN will rise in this design? You will need to make sure the voltage ratings are not exceeded for VIN and EN pin if EN is powered through VIN.

Hello Amod,

The voltage at the VIN pin is from 0V to 3.3V in <1ms. Will that be acceptable? The EN pin is supplied by 1.8V from a different source.

Thanks!

Hi Jared,

There is no limit as such on the slew rate so the 3.3V in 1ms or lower is acceptable. Curious to know why you are using a 17V rated device for a 3.3V input?
