FAIRCHILD SEMICONDUCTOR FSQ500L 芯片, 配电开关, PWM, FET, 3W, 4SOT223
The is an Integrated Power Switch Pulse Width Modulator with 130kHz frequency and no bias winding for 2.5W offline fly-back converters. It is specially designed for a replacement of linear power supplies. This device combines current-mode Pulse Width Modulator PWM with a sense-FET. The integrated PWM controller features a fixed oscillator, under voltage lockout UVLO protection, overload protection OLP, leading-edge blanking LEB, an optimized gate turn-ON/OFF driver, thermal shutdown TSD protection with hysteresis and temperature-compensated precision-current sources for loop compensation. When compared to a linear power supply, the FSQ500L device reduces total size and weight, while increasing efficiency, productivity and system reliability. This device provides a basic platform for fly-back converters.
