KA1H0165RN/KA1H0165R Fairchild Power Switch FPS • Precision Fixed Operating Frequency 100kHz • Pulse by Pulse Over Current Limiting • Over Load Protection • Over Voltage Protection Min. 23V • Internal Thermal Shutdown Function • Under Voltage Lockout • Internal High Voltage Sense FET • Auto Restart Mode The Fairchild Power Switch FPS product family is specially designed for an off line SMPS with minimal external components. The Fairchild Power Switch FPS consist of high voltage power SenseFET and current mode PWM controller IC. PWM controller features integrated fixed oscillator, under voltage lock out, leading edge blanking, optimized gate turn-on/turn-off driver, thermal shut down protection, over voltage protection, temperature compensated precision current sources for loop compensation and fault protection circuit compared to discrete MOSFET and controller or RCC switching converter solution The Fairchild Power Switch FPS can reduce total component count, design size, weight and at the same time increase & efficiency, productivity, and system reliability. It has a basic platform well suited for cost effective design in either a flyback converter or a forward converter. 8-DIP TO-220F-4L Internal Block Diagram Drain GND VCC F/B S/S GND Drain VCC F/B * Soft Start Internal Vref bias Good logic 5µA 1mA 2.5R 9V 1R − + L.E.B 0.1V 7.5V − + Thermal S/D 25V − OVER VOLTAGE S/D Power on reset * KA1H0165RN 2003 Fairchild Semiconductor Corporation SFET DRAIN GND KA1H0165RN/KA1H0165R Absolute Maximum Ratings Parameter Maximum Drain Voltage 1 Drain-Gate Voltage Gate-Source GND Voltage Drain Current Pulsed 2 Single Pulsed Avalanche Energy 3 Continuous Drain Current TC=25°C Continuous Drain Current TC=100°C Maximum Supply Voltage Input Voltage Range Total Power Dissipation Symbol VD,MAX VDGR VGS IDM EAS ID VCC,MAX VFB PD Darting Operating Ambient Temperature Storage Temperature TA TSTG Notes Tj = 25°C to 150°C Repetitive rating Pulse width limited by maximum junction temperature L = 80mH, VDD = 50V, RG = starting Tj = 25°C Value 650 ±30 95 30 to VSD 40 -25 to +85 -55 to +150 Unit V ADC mJ ADC V W/°C °C °C KA1H0165RN/KA1H0165R Electrical Characteristics SFET Part Ta=25°C unless otherwise specified Ordering Information Product Number KA1H0165RN KA1H0165R-TU KA1H0165R-YDTU TU Non Forming Type YDTU Forming Type Package 8-DIP TO-220F-4L Rating 650V, 1A 650V, 1A Operating Temperature -25°C to +85°C -25°C to +85°C KA1H0165RN/KA1H0165R KA1H0165RN/KA1H0165R DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
