Description

The NCL30000 is a power factor corrected LED driver controller. This evaluation board manual describes the setup and operation of the NCL30000LED1GEVB LED driver for 115 V input. The evaluation board implements an isolated single stage Critical conduction Mode (CrM) flybackconverter providing a regulated constant current to an LED load. This board has been specifically configured to support leading and trailing edge line dimming and has been characterized across a range of commercially available dimmers. The output voltage range is suitable for nominal 4 to 15 high brightness power LEDs. Protection features include open load protection, over temperature protection, and overload limiting. As shipped, the evaluation board is set up for the following parameters:

Features

  • Input Voltage Range: 90−135 Vac
  • Output Current: 350 mA 5%
  • Output Voltage Range: 12−50 Vdc
  • Output Power: up to 17.5 W
  • Full Load Efficiency: >83%
  • Power Factor: >0.95 Typical
  • 50C Ambient Operation
  • Class B Conducted Emissions
  • Compatible with Triac and Electronic Dimmers
