FS7M0680 Fairchild Power Switch FPS • Precise Fixed Operating Frequency • FS7M0680 66kHz • Pulse By Pulse Current Limiting • Over Current Protection • Over Load Protection • Over Voltage Protection Min. 25V • Internal Thermal Shutdown Function • Under Voltage Lockout with Hysteresis • Internal High Voltage Sense FET • Latch Up Mode • Soft Start The Fairchild Power Switch FPS product family is specially designed for an off line SMPS with minimal external components. The Fairchild Power Switch FPS consists of high voltage power SenseFET and current mode PWM controller. The PWM controller includes integrated fixed oscillator, under voltage lock out, leading edge blanking block, optimized gate turnon/turn-off driver, thermal shut down protection, over voltage protection, temperature compensated precise current sources for loop compensation and fault protection circuit. Compared to discrete MOSFET and PWM controller or ring choke converter RCC solutions, the Fairchild Power Switch FPS can reduce total cost, component count, size and weight simultaneously increasing efficiency, productivity, and system reliability. It has simple applications well suited for cost down design for flyback converter or forward converter.
