SY50133 Flyback Regulator

SY50133 is a single stage Flyback controller targeting at Constant Current/Constant Voltage (CC/CV) applications. It integrates a 600V MOSFET to decrease physical volume. Both the output current and voltage are sensed by primary side signal process. SY50133 operates quasi-resonant mode and adaptive.

SY50133 Features

* Very tight PSR CC/CV regulation over entire operating range

* QR-mode operation for high efficiency

* PWM/PFM control for higher average efficiency

* Internal CC/CV loop compensation

* The self-adaption compensation for better stability

* Fast dynami
