OB3330

OB3330 High Performance LED Lighting Driver GENERAL DESCRIPTION The OB3330 is power factor correction, primary-side-control LED lighting driver with advanced features to provide high efficiency control for lighting applications. OB3330 features an internal start-up timer for stand-alone applications, an analog multiplier for power factor correction (PFC), zero current detectors (ZCD) to ensure transition mode (TM) operation, a current sensing comparator with built-in leading-edge blanking, and a totem pole output. OB3330 offers great protection coverage including VCC under voltage lockout (UVLO), VCC over voltage protection, load voltage over voltage protection, Level selectable cycle-by-cycle current limiting, over temperature protection, LED open/short circuit protection and gate drive output clamping for external power MOSFET protection.
