توضیحات

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
