KA5x0365RN-SERIES KA5M0365RN, KA5L0365RN Fairchild Power Switch FPS • Precision Fixed Operating Frequency 67/50kHz • Low Start-up Current Typ. 100uA • Pulse by Pulse Current Limiting • Over Current Protection • Over Voltage Protection Min. 25V • Internal Thermal Shutdown Function • Under Voltage Lockout • Internal High Voltage Sense FET • Auto-Restart Mode • SMPS for VCR, SVR, STB, DVD & DVCD • SMPS for Printer, Facsimile & Scanner • Adaptor for Camcorder 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 a high voltage power SenseFET and a current mode PWM IC. Included PWM controller integrates the fixed frequency oscillator, the under voltage lock-out, the leading edge blanking, the optimized gate turn-on/turn-off driver, the thermal shutdown protection, the over voltage protection, and the temperature compensated precision current sources for the loop compensation and the fault protection circuitry. Compared to a discrete MOSFET and a PWM controller or an RCCsolution, a Fairchild Power Switch FPS can reduce the total component count, design size and weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for the cost effective design in either a flyback converter or a forward converter 8-DIP Internal Block Diagram Drain 2.GND 3.Vcc 4.FB 5.NC #3 VCC #4 FB Internal Vref bias Good logic 5µA 7.5V 27V 9V 1mA 2.5R L.E.B 0.1V + Thermal S/D − OVER VOLTAGE S/D Power on reset 2003 Fairchild Semiconductor Corporation SFET #1,6,7,8 DRAIN Absolute Maximum Ratings Ta=25°C, unless otherwise specified Characteristic KA5M0365RN, KA5L0365RN Drain-Gate Voltage Gate-Source GND Voltage Drain Current Pulsed 1 Continuous Drain Current Ta=25°C Continuous Drain Current Ta=100°C Single Pulsed Avalanche Energy 2 Maximum Supply Voltage Analog Input Voltage Range Total Power Dissipation Operating Junction Temperature.
