Toote ülevaade

The STEVAL-ILL044V1 is a demo board to evaluate HVLED815PF LED driver chip. This board solves the problem of low cost drive circuitry for LED replacements for 40W incandescent or equivalent compact fluorescent lamps. The HVLED815PF is a new integrated power controller using primary side control to achieve LED current regulation within +/-5% (It also has primary side voltage regulation, used here for open load protection). The device incorporates an 800V avalanche rated FET and an internal startup circuit eliminates the need for external rapid start circuitry. The PFC flyback power converter operates in transition mode for the highest efficiency and best use of components. With the addition of a few extra components the HVLED815PF is made to draw near sinusoidal input current from the AC line. The circuit regulates LED current over a wide range of line voltage and LED string voltage and is dimmable with standard triac based dimmers.
  • Fully isolated output
  • Low component count
  • Only one tight tolerance component
  • High efficiency, greater than 86%
  • High power factor, greater than 0.98
  • Low THD, less than 20% over 90V to 132V range
  • Fits in 28mm tubing
  • 9W output, for light equal to a range from 40W to 60W incandescent
  • Startup within 0.2sec
  • Dimmable over 90V to 132V voltage range
