This document describes the features and characteristics of the STEVAL-ILL016V2, a 15 watt regulated Triac-dimmable LED driver from STMicroelectronics. The driver is designed for the North American (115V) market and can drive strings of 4 to 12 jumper-selectable white LEDs connected in series. It has a maximum current of 1A (preset for 350mA as shipped), an undimmed power factor greater than 0.9, LED current ripple less than 20% P-P, and an isolated output for safe LED heatsinking. The driver is RoHS compliant.
