BP3337E Datasheet | BPS

High PF PSR LED Driver General Description Features BP3337E is a high PF PSR constant current LED - driver with high current accuracy. It is suitable for - 90Vac-277Vac universal input. - BP3337E achieve high PF by constant on time - control. With internal THD optimizer, the THD of - input current can be further reduced. BP3337E - works in BCM mode, which can help to improve - switching loss and EMC performance. - - BP3337E adopts DIP-7 package. - - - 90-277Vac universal input High PF low THD (PF>0.9，THD<15%) Support two-winding design for isolated application High accuracy of current reference (+/-3%) Good line and load regulation Critical conduction mode Low operation current VCC UVLO Cycle by cycle current limitation Output open/short protection Thermal fold back DIP-7 package Applications - LED Driver - High-Performance LED Fixture Typical Application 1 VCC DRAIN 7 2 FB DRAIN 6 3 GND 4 P CS 5 Fig. 1 Typical Schematic Diagram BP3337E_EN_DS_Rev.1.0 .bpsemi.
