AN-4103 A Fairchild Power Switch (FPS) Based Switched Mode Power Supply for Monitor Usewww.fairchildsemi.com Application Note AN4103 An Fairchild power Switch(FPS) Based Switched Mode Power Supply for Monitor Use 1. Introduction This application note describes a flyback converter using the Fairchild Power Switch (FPS) in a switched mode power supply (SMPS) for a monitor. The Fairchild Power Switch (FPS) integrates a MOSFET and its control IC into one package, incorporating all of the required protection circuitry on chip. This simplifies the design of the SMPS, which now requires fewer components, enhancing reliability and increasing manufacturing productivity. Further, a smaller component count increases reliability and therefore decreases the cost of field maintenance. This application note reviews monitor SMPS design considerations focusing on the features of the new KA……
