Overview

BP3319M PSR Single-Stage APFC Offline LED Controller Description The BP3319M is a high precision primary-side regulation PWM controller with single stage Active PFC, specially designed for universal input offline flyback or buck-boost constant current LED lighting.
The controller with on-chip PFC circuit achieves high power factor and low THD.
Operating in critical conduction mode, the power MOSFET switching loss is reduced and the inductor is fully utilized.
The BP3319M adopts proprietary primary side current sensing scheme.
It can precisely control the LED current without secondary side sense and feedback circuits.
The system size and cost are optimized, as well as the system reliability.
