DRV8718-Q1: Maximum PWM frequency

Hello, I am wondering about using one of these to control the voltage/current in four high power Peltier TEC modules (each 24V ~8Amp)

In order to keep the inductors small I want to use the highest PWM frequency possible but cannot find anywhere in the data-sheet or forums which states the maximum acceptable frequency of PWM the device can accept.

Can someone please help me (or advise of some other chip if this is not the most suitable).

Thanks in advance, Ben
