©2000 Fairchild Semiconductor International www.fairchildsemi.com Rev. .5.0 Features • Precision fixed operating frequency • KA1M0565R (67KHz),KA1H0565R (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 Description The SPS product family is specially designed for an off-line SMPS with minimal external components. The SPS consist of high voltage power SenseFET and current mode PWM controller IC. PWM controller features integrated fixed oscil- lator, under voltage lock out, leading edge blanking, opti- mized 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 con- troller or RCC switching converter solution, a SPS 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 effec- tive design in either a flyback converter or a forward con- verter. TO-220F-4L 1. GND 2. DRAIN 3. VCC 4.
