L6566BH IC-COMP pin V-I characterstics
2020-10-15
Can anyone explain me, how internally COMP pin voltage of IC is regulated by changing current sunk from pin.Thanks
I designed 300V-800V to 24V,4A flyback converter using L6566BH. With RCD snubber of 470kΩ,2.2nF values, the converter is fine except switch stress of about 1500V at full load. To reduce it when I changed snubber to 235kΩ,4.4nF, IC got failed.

Is there any probable reason and solution for it?
I have started working on flyback converters with L6566BH controller IC. Do you have some spice model and PCB design guidelines for this IC?
