PT4219 - Primary Side Offline LED Controller

PT4219 Description

PT4219 Primary Side Offline LED Controller with Active PFC GENERAL .
The PT4219 is a primary side constant current controller which can achieve high power factor in a single stage converter, targeted to applications in.

PT4219 Features

* Constant Current Control Without Secondary Feed back Accurate Constant Current Output Quasi-Resonant Mode Operation Ultra-low（10uA）Start Up Current Low Quiescent Current (1mA) VCC Under Voltage Protection Over Voltage Protection

PT4219 Applications

* in solid state lighting. It is designed for the flyback topology, and regulates output current accurately without the secondary feedback loop. PT4219 works in quasi-resonant mode to reduce the MOSFET switching loss. The device uses extremely low startup and low quiescent current to achieve high effi
