LED Driver, Dimmable, Power Factor Corrected

Favorite

Overview

The NCL30000 is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected isolated flyback LED Drivers. It employs a Critical Conduction Mode (CrM) control technique to ensure near unity power factor across a wide range of input voltages and output power.

  • <40 W single stage high power factor constant current drivers
  • Commercial and residential LED fixtures
  • LED driver power supplies
  • LED-based down lights
  • TRIAC dimmable LED-based PAR lamps
  • Power factor corrected constant voltage supplies
  • Constant on-time PWM control
  • Cycle-by-cycle current protection
  • Low current sense threshold of 500 mV
  • Reference design for TRIAC line dimmers
  • Source 500 mA / Sink 800 mA totem pole gate driver
  • Low 2.0 mA typical operating current
  • Very low 24 µA typical startup current
  • PbFree, halogen free/BFR free and RoHS compliant
