TPS4H000-Q1: switching frequency - what is the max PWM input?

Hello Josh, 

TI HSS are limited to operating at 1-2kHZ PWM frequency. Below is application note on Driving PWM Loads with TI High-Side Switches.

If a higher frequency is required this can be accomplished by reassigning the PWM switching duties from the HSS to a separate low-side switch.

Best, 

Alan
