The STEVAL-ILL045V1 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 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 it is dimmable with standard Triac-based dimmers.

Key features
  • 9 W output, for light equal to a range from 40 W to 60 W incandescent
  • +/-5% primary-side current regulation, no optocoupler
  • Low component count - 25 parts, including the EMI filter
  • Only 1 tight-tolerance component
  • High efficiency, > 86%
  • High power factor > 0.98 and low THD, < 20% over 90 V to 132 V range
  • Fits in 28 mm tubing, 52 mm overall length
  • Dimmable with common Triac dimmer
  • RoHS compliant
