NCP1362 Primary Side PWM Controllers

onsemi NCP1362 Primary Side PWM Controllers deliver a highly integrated primary side quasi-resonant flyback controller that controls rugged, high-performance off-line power supplies. The NCP1362 implements the Novel Method, reserving the secondary feedback circuitry for Constant Voltage and Constant Current regulation. This feature allows excellent line and load regulation without a traditional optocoupler and TL431 voltage reference.
