Hi,
We are doing 100W buck. Vin = 200V, Vout = 36V, Fsw = 150kHz.
The FET is low side, (easy to drive) and the controller is grounded at the input connector ground.
As such, we need opto feedback.
But AYK, the opto, from diode side to transistor side, will see rapid dv/dt.
So we need a feedback opto with high CMTI, but no feedback opto's list this parameter.
eg CNY17-2
FOD817
FODM121
Do you know of feedback opto's which do list this parameter?
