An 80A pulse width modulator is too high of amperage for any that I've seen. I'm sure your refering to high voltage and a low impedance. But either way it's going to be a larger circuit. Logic devices and reactive components are used to produce the initial PWM signal

>80A is PWM pretty common in motor control circuits for small electric vehicles such as golf buggies. Large vehicles such as cars require surges of over 1kA but they normally uses AC motors rather than DC.

VRM's go even higher... ~100A

Not really!
