STEVAL-ILL045V1: 120 V A19 dimmable high power factor 9 W

LED driver using the HVLED815PF

By Thomas Stamm

Introduction

The STEVAL-ILL045V1 demonstration board showcases ST's new HVLED815PF LED

driver chip. 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 highest efficiency and best

use of components. With the addition of a few extra components the HVLED815PF draws

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.
