This application note describes a complete flyback switched mode power supply that uses a Fairchild Power Switch. The MOSFET and its control IC are built into one package. The MOSFET is in fact a SenseFET. Various protection features are also included. Fairchild Power Switch can enhance the reliability and productivity of the system when compared to other designs. The FS6M series has a more avalanche rugged SenseFET than the previous Fairchild Power Switch series. The FS6M series features include burst mode operation for low power consumption in DPMS mode. This application note describes the features and design considerations of the FS6M series for the LCD monitor power supply and adaptor, which improves upon the existing KA5X-series.
