DESCRIPTION
control IC features a trimmed oscillator, under voltage lock-out, leading edge blanking, optimized gate turnon/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, 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-effective Monitor power supply. TO-3P-5L 1 1. DRAIN 2. GND 3. Vcc 4. FB 5. Sync Internal Block Diagram #3 VCC 32V 5V Vref − 5V + 6.4V #4 FB − 1mA...
