Publication number: 20110141778Abstract: A switch controller for switching power supply is coupled to an auxiliary winding of the switching power supply through a detecting resistor. The switch controller provides a detecting current passing through the detecting resistor for keeping the voltage level of a detecting signal transmitted by the detecting resistor higher than a predetermined voltage. In this way, the switch controller can avoid the latch-up phenomenon caused by receiving the detecting signal of the negative voltage level. In addition, the switch controller can detect the magnitude of an input voltage of the switching power supply by means of the detecting current, and accordingly control the operation of the switching power supply.Type: ApplicationFiled: October 24, 2010Publication date: June 16, 2011Inventors: Tsung-Hsiu Wu, Wen-Chung Yeh, Ming-Nan Chuang
