FS8S0765RCB Fairchild Power Switch FPS April 2006 FS8S0765RCB Fairchild Power Switch FPS - Burst Mode Operation to Reduce the Power Consumption in the Standby Mode - External pin for Synchronization and Soft Start - Wide Operating Frequency Range up to 150kHz - Low Start-up Current Max:80uA - Low Operating Current Max:15mA - Pulse by Pulse Current Limiting - Over-Voltage Protection Auto Restart Mode - Overload Protection Auto Restart Mode - Abnormal Over-Current Protection Auto Restart Mode - Internal Thermal Shutdown Auto Restart Mode - Under-Voltage Lockout - Internal High-Voltage SenseFET - SMPS for Monitor FS8S0765RCB is a Fairchild Power Switch FPS that is specially designed for off-line SMPS of CRT monitors with minimal external components. This device is a current mode pulse-width modulated PWM controller combined with a high-voltage power SenseFET in a single package. The PWM controller features integrated oscillator to be synchronized with the external sync signal, under-voltage lockout, optimized gate driver, temperature compensated precise current sources for the loop compensation. This device also includes various fault-protection, circuits such as over voltage protection, overload protection, abnormal over current protection and over-temperature protection, Compared with a discrete MOSFET and PWM controller solution, FPS can reduce total cost, component count, size, weight, while increasing efficiency, productivity, and system reliability. This device is well suited for the cost-effective monitor power supply.
