TPS1H000-Q1: Max Switching Frequency

Part Number: TPS1H000-Q1

Hello,

What is the highest PWM frequency we could drive this switch with? This is a 12V application.

I noticed the switching delays in the datasheet and tried to do a worst case analysis.

90us turn on delay + 120us rise time + 90us turn off delay + 40us fall time = 340us = ~2.9kHz.

It seems that's a theoretical max and to prevent problems we should probably stay below that. But how far below? 

I hope that makes sense, and thank you for any help.

Regards,
Ryan B.
