Overview

OB3330X is a primary-side feedback LED constant-current driver controller with high power factor correction, designed for flyback isolated LED lighting applications. Eliminates the need for secondary-side components such as TL431 and optocouplers. Operating in critical conduction mode to minimize switching losses and maximize efficiency.

Applications

Industrial and commercial LED lighting
Residential LED lighting

Key features

Single-stage PFC with primary-side feedback control
Critical conduction mode for high efficiency
Analog multiplier for power factor correction
High constant-current accuracy
Cycle-by-cycle peak current limiting with configurable threshold
Soft-start function
Ultra-low startup current (TYP. 5uA)
Minimized system design
LED open-circuit protection
LED short-circuit protection
VCC overvoltage protection
VCC undervoltage protection
Output load overvoltage protection
Over-temperature protection
Features include soft-start, power factor correction, constant-current control, zero-current detection, leading-edge blanking (LEB) built into current sense comparator, and totem-pole output driver
Comprehensive protection features including LED open/short-circuit protection, VCC overvoltage and undervoltage protection, output load overvoltage protection, cycle-by-cycle peak current limiting with user-configurable threshold, over-temperature protection, and output driver clamping for power MOSFET protection
