Abstract:
A power controller provides open-circuit protection for a power supply when an open circuit occurs between a ground end of an auxiliary winding and an input ground. The power controller provides a PWM signal to determine an ON time and an OFF time of a power switch connected in series between an input voltage and the input ground. A deviation detector in the power controller detects a winding voltage at a floating end of the auxiliary winding during the ON time, and asserts an open protection signal when a variation of the winding voltage during the ON time fits a first predetermined condition, so as to keep the power switch turned OFF and provide the open-circuit protection.

Claim (Index 12):
The control method as claimed in  claim 10 , comprising:\n counting how many times the feedback current has been less than the register current and accordingly providing a count; and asserting the open protection signal when the count is equal to a predetermined number.
