BP3336B Datasheet | BPS

Description BP3336B is a high PF PSR constant current LED driver with high current accuracy. It is integrated with 650V MOSFET and is suitable for 90Vac-277Vac universal input. BP3336B realizes high PF by constant on time control. With internal THD optimizer, the THD of input current can be lower than 15% under universal input. BP3336B works in BCM mode, which can help to improve switching loss and EMI performance. With internal HV start up and fast start up control, BP3336B can build up output current within 500ms. With internal line and load pensation, BP3336B can achieve excellent line and load regulation. BP3336B can work as floating buck-boost with singlewinding inductor or isolated Flyback topology with two or three windings transformer.
