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. FEATURES  Primary-Side Control with Single Stage PFC Topology  Minimized BOM Count  Transition Mode (TM) Operation to Achieve High Efficiency  Analog multiplier for Power Factor Correction  High Current Accuracy  Cycle-by-Cycle Current Limiting (OCP)  Selectable Threshold of OCP  VCC Over Voltage Protection  Output Over Voltage Protection  Over-temperature Protection  LED Open Circuit Protection  LED Short Circuit Protection  Soft-start  VCC Under Voltage Lockout (UVLO)  Ultra-low Start-up Current APPLICATIONS  LED Lighting  Industrial and Commercial lighting  Residential lighting TYPICAL APPLICATION On-Bright Confidential to Figure1: OB3330 Typical Application Schematic ©On-Bright Electronics Confidential -1- Preliminary Datasheet OB_DOC_DS_333000 On-Bright Confidential to Absolute Maximum Ratings Parameter VCC Input Voltage to GND GATE to GND I/O (except GATE) to GND Operating Ambient Temp.
