Other Parts Discussed in Thread: PMP11155,
Dear Team,
I would like to know the working of startup network in PMP11155.
Working voltage of Vcc is 20V but as per resistor network Vcc net will have 41V while input voltage is 90Vac.
Once the IC starts operating, how does Vcc change over from HV net to bias winding.
Thanks in advance.
Warm Regards.
