General Description

The QH7935 is a high precision primary-side regulation driver with single stage Active PFC, specially designed for universal input offline flyback or buck-boost constant current LED lighting.

The driver 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 Integrated 650V Power MOSFET ±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-voltage and Under-voltage Protection Auto.
