9 W Triac dimmable, high power factor, isolated LED driver based on the HVLED815PF (for US market)

The STEVAL-ILL044V1 demonstration board showcases ST’s new LED driver chip, HVLED815PF. It solves the problem of low-cost drive circuitry for LED replacements for 40 W 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 800 V avalanche-rated FET and fits in a standard SO-16 package. 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.

Key Features

  • +/- 5% primary-side current regulation, no optocoupler
  • Fully isolated output
  • Low component count
  • Only 1 tight-tolerance component
  • High efficiency, >86%
  • High power factor >0.98
  • Low THD, < 20% over 90 V to 132 V range
  • Fits in 28 mm tubing
  • 9 W output, for light equal to range from 40 W to 60 W incandescent
  • Startup within 0.2 seconds
  • Dimmable over 90 V to 132 V voltage range
  • RoHS compliant
