FS8S0765RCB Fairchild Power Switch (FPSTM)
Features
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:80A) 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

Description
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.
