Product details

Description

The PT4219 is a primary side constant current controller which can achieve high power factor in a single stage converter, targeted to applications in solid state lighting.

It is designed for the flyback topology, and regulates output current accurately without the secondary feedback loop.

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 by Voltage Holding Cycle by Cycle Current Limit Rcs Open Circuit Protection Transformer Winding Short Circuit Protection Output Open/Short Circuit Protection Over Temperature Protection.
