Description
Primary Side Offline LED Controller

Features

* Constant Current Control Without Secondary Feed back Flicker-free PWM/analog Dimming (10%-100%) Accurate Constant Current Output Quasi-Resonant Mode Operation Ultra-low(10uA)Start Up Current Low Quiescent Current (1mA) VCC

Applications

* in solid state lighting. It is designed for the flyback topology, and regulates output current accurately without the secondary feedback loop. PT4209 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
