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.
