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 12):
A method for controlling a power supply; the power supply comprising a switching element, a transformer with a primary winding and a secondary winding, and a rectifying diode connected to the secondary winding;\n wherein the method comprises: filtering, using a smooth filtering circuit and a snubber circuit, at least one of a ringing voltage and a surging voltage of a voltage signal in the primary winding and passing a voltage greater than a reference voltage to generate a filtered voltage signal; delaying the filtered voltage signal and generating a delayed voltage signal; and sampling and holding the delayed voltage signal after a time when the rectifying diode stops conducting a current, and to output a feedback signal used for controlling the switching element.
