Primary Side PWM Controller for Low Power Offline SMPS

Overview

The NCP1362 is a new quasi−resonant peak current mode control mode controller targeting output power levels from a few watts up to 50 W in a flyback application. It is primary side regulated for Constant Voltage and Constant Current regulation, achieving excellent line and load regulation without requiring the typical opto-coupler and voltage reference.
