BP3336B is a high PF PSR constant current LED driverwith high current accuracy. lt is integrated with 650VMOSFET and is suitable for 90Vac-277Vac universainput.
BP3336B realizes high PF by constant on time control.With internal THD optimizer, the THD of input currentcan be lower than 15% under universal input.BP3336B works in BCM mode,which can help toimprove switching loss and EMl performance.With internal HV start up and fast start up control,BP3336B can build up output current within 500ms.With internal line and load compensation, BP3336Bcan achieve excellent line and load regulation.
BP3336B can work as floating buck-boost with singlewinding inductor or isolated Flyback topology withtwo or three windings transformer.BP3336B is available in SOP-8 package.
