Abstract:
A device and method for controlling a power supply. The method includes: a voltage signal in a primary winding is delayed, and the delayed voltage signal is sampled and held after a time when a rectifying diode stops conducting a current, then the sampled and held signal is used as a feedback signal of the power supply. Therefore, only one sampling and holding circuit is needed, the area of the circuit can be reduced and the cost of the integrated circuit can be decreased, meanwhile regulation characteristics are not deteriorated.

Claim (Index 14):
The method according to  claim 12 , wherein the method further comprises:\n comparing the feedback signal and a reference signal to generate an error signal; and generating a driving signal based on the error signal to control the switching element.
