This is an isolated, 25W, 0-10V dimmable LED driver design with >0.9 power factor (PF) which meets or exceeds commercial lighting PF and total harmonic distortion (THD) requirements.  It is well suited for integral LED luminaires, or ballasts, that use high-brightness LED emitters.  This design is optimized for a 500mA (max) LED output current and LED stack voltages ranging from 45 V to 55 V.

  • 100-264VAC Input, 25W ouput, Single Stage LED Driver with Active Power Factor Correction (>0.9)
  • 500mA Constant Current Output with < +/- 4% LED Current RegulationFast Startup < 500ms
  • Fast Startup < 500ms
  • Operates with Standard 0-10V Dimmers with 9:1 Contrast Ratio
  • Fully Tested Design for Use in Integral LED Downlight/Troffer Fixtures or as Stand Alone LED Driver Module
