KA3S0680-Fairchild Power Switch (FPS)
DESCRIPTION Fairchild's Power Switch (FPS) product family is specifically designed for off-line switching power supplies with minimal external components. Fairchild's power switch (FPS) consists of a high voltage value SenseFET and a current mode PWM controller IC. The controller IC features trimmed oscillator, undervoltage lockout, leading edge blanking, optimized gate turn-on/turn-off drive, thermal shutdown protection, overvoltage protection, temperature compensation precision for loop compensation and fault protection current source circuits. Compared to discrete MOSFET and controller or RCC switching converter solutions, a Fast Power Switch (FPS) can reduce total component count, reduce design size, weight, and at the same time increase efficiency, productivity and system reliability. it has a basic
Features • Wide operatimg frequency range (150kHz)
• Pulse through pulse current limit and more • Overload protection JOURNAL • Overvoltage protection (min. 23V)
•Internal thermal shutdown function •Under voltage lockout •Built-in high voltage sensing FET •External sync terminal •Auto restart mode
