Hello everybody,
I try to use IR2117 gate driver to drive mosfet (IRF540 or IRFP240) in high side and not sucess. I can only get a little VB-Vs voltage, around 1.8V. I use BYV27-150 diode and I tuned different capacitor values from 0.5uf to 0.005uf. There is no VB-VS voltage when cap's value go larger.
Does anyone have help in it, thanks,
Raychar
