NCP1362 Overview
Primary Side PWM Controller for Low Power Offline SMPS NCP1362 The NCP1362 is a highly integrated primary side quasi−resonant flyback controller capable of controlling rugged and high−performance off−line power supplies. Due to a Novel Method this new controller saves the secondary feedback circuitry for Constant Voltage and Constant Current regulation, achieving excellent line and load regulation without...
