Is there any class D amplifier that is fast enough to have 50V/us or above? So i am expecting the output pwm is beyond 2.5Mhz.
So i am looking for an chip Class D that able to work over 200khz, and if possible DC output too!
I have bought some irs2092, TPA3255, but their output is just around 400~500khz.
Attached is the output that i wish to generate, and the load will be very low.
I have tried to drive with 4xparallel LME49600, surprisingly they cant do the job.

Looks very much like you are trying to recreate the drain waveform on a single/two switch forward/flyback convertor?
I know that waveform. It's from a piezoelectric printhead 🙂 The original design actually switches up to 5MHz.
I have used ganfet with some success to replicated the waveform, but I do not have time to debug everything. Class AB with heatsink and some airflow work fine for us.
