onsemi NCL3018x AC-DC Controllers

onsemi NCL3018x AC-DC Controllers are analog/digital dimmable and power factor corrected current-mode controllers. These controllers support flyback, buck-boost, and Single-Ended Primary-Inductor Converter (SEPIC) topologies and target isolated and non-isolated constant current LED drivers. onsemi NCL3018x controllers come in a compact SOIC package and are highly integrated with a minimum number of external components. These quasi-resonant controllers operate at a temperature range of -40°C to +125°C and supply voltage of 8.2V to 9.4V. The NCL3018x controllers are RoHS compliant, lead-free, and halide-free.

Features

  • Quasi-resonant peak current-mode control operation
  • Valley lockout optimizes efficiency over the line/load range
  • Constant current control with primary side feedback
  • Tight LED constant current regulation of ±2% (typical)
  • Line feedforward for enhanced regulation accuracy
  • Low start-up current (10µA typical for NCL185 and NCL186)
  • Low start-up current (13µA typical for NCL188)
  • 300mA/500mA totem pole driver with 12V gate clamp
  • Robust protection features
    • Brown-out detection
    • Over voltage protection on VCC
    • Programmable over voltage/LED open circuit protection
    • Winding short circuit protection
    • Output short circuit protection
    • Thermal shutdown

Applications

  • Integral LED bulbs
  • LED light engines
  • LED driver power supplies
  • Smart LED lighting applications
