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.
