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.

Key Features

  • Single-Stage Active PFC for High Power Factor and Low THD.
  • Primary Side Control Constant Current Operation, No Opto-Coupler required.
  • ±3% LED Current Accuracy.
  • Excellent Line and Load Regulation.
  • Critical Conduction Mode Operation.
  • Ultra-Low (33uA) Startup Current.
  • High Resistance Feedback Resistor for Improved Efficiency.
  • LED Open and Short Circuit Protection.
  • CS Resistor Open Circuit Protection.
  • Cycle-by-Cycle Current Limit.
  • VCC Over-volt.
