General Description

The BP3319MB 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.

Overview
