Description
PT4219 Primary Side Offline LED Controller with Active PFC GENERAL .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 ProtectionApplications
* 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 effiPT4219 Distributors
