OB3330
High Performance LED Lighting Driver
GENERAL DESCRIPTION
FEATURES
The OB3330 is power factor correction, Primary-Side Control with Single Stage PFC
primary-side-control LED lighting driver with
Topology
advanced features to provide high efficiency Minimized BOM Count
control for lighting applications.
Transition Mode (TM) Operation to Achieve
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.
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
OB3330 offers great protection coverage including LED Open Circuit Protection
VCC under voltage lockout (UVLO), VCC over LED Short Circuit Protection
voltage protection, load voltage over voltage Soft-start
protection, Level selectable cycle-by-cycle current
limiting, over temperature protection, LED
open/short circuit protection and gate drive output
tial to clamping for external power MOSFET protection.
VCC Under Voltage Lockout (UVLO)
Ultra-low Start-up Current
