Part # KA5Q12656RTH datasheet

Part Manufacturer: Motorola


Part Description: KA5Q1265RFH KA5Q12656RTH Fairchild Power Switch(FPStm)

Part Details: KA5Q1265RFH/KA5Q12656RTH Fairchild Power Switch(FPS) Features Description · Quasi Resonant Converter Controller The Fairchild Power Switch(FPS) product family is specially · Internal Burst Mode Controller for Stand-by Mode designed for an off-line SMPS with minimal external · Pulse by Pulse Current Limiting components. The Fairchild Power Switch(FPS) consists of a · Over Current Latch Protection high voltage power SenseFET and a current mode PWM IC. · Over Voltage Protection (Vsync: Min. 11V) The integrated PWM controller includes the fixed oscillator, · Internal Thermal Shutdown Function the under voltage lock out, the leading edge blanking, the · Under Voltage Lockout optimized gate turn-on/turn-off driver, the thermal shut down · Internal High Voltage Sense FET protection, the over voltage protection, and the temperature · Auto-Restart Mode compensated precision current sources for loop compensation and fault protection circuitry. Compared to a discrete MOSFET and a controller or a RCC switching converter solutions, a Fairchild Power Switch(FPS) can reduce the total number of components, design size, and weight, so it will improve efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective design in a quasi-resonant converter as a C-TV power supply. TO-3PF-5L TO-220F-5L 1. Drain 2. GND 3. Vcc 4. Feedback 5.
