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.
