Datasheet Summary
OB3332Bx
Single Winding, High PF Non-Isolated dimmable LED driver
GENERAL DESCRIPTION
OB3332Bx is a TRIAC dimmable high power factor, highly integrated buck/buck-boost regulator with advanced Features to provide high efficiency control and high precision constant current output for dimmable LED lighting applications. The proprietary CC control scheme is used to provide Features of insensitivity to inductance and line voltage. Without external large pensation capacitor, the system can achieve high power factor with proprietary PFC control scheme. OB3332Bx offers prehensive protection coverage with auto-recovery Features including LED open loop protection, LED short circuit...
