Vmain = 3V
VGH = 20V
VGL = -7V
Vmain is coming up correctly. However, VGH is reading 0V and…

Please excuse the late response.
The fault protection threshold is around 90% of the nominal value for Vmain and VGH. When FBL is above roughly 110mV, the protection on VGL will turn on.
Best regards, Brigitte
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
