STEVAL-ILL070V1

STEVAL-ILL070V1 35 W, 0-10 V dimmable single-string LED driver based on the HVLED001 quasi resonant flyback controller Data brief Description Features          Input voltage: VIN = 90 to 305 Vrms, 45 to 66 Hz Output current: 700 mA (VLED = 0 to 48 V) Dimming: 100% to 10% (any condition) Dimming interfaces: 0 to 10 V and PWM input High power factor, low THD Efficiency: > 90% @ full load No-load: better than 300 mW @ 230 VIN Open load voltage limiting RoHS compliant February 2015 The STEVAL-ILL070V1 is an evaluation platform that drives a single LED string with a maximum output current of 700 mA. The LED current can be finely adjusted using either a 0 - 10 V interface or a PWM signal (provided by a microcontroller, for example) on the SELV portion of the board. The extremely wide output voltage range and the universal input capability make this board very flexible. An auxiliary 12 V output is also present to supply small circuitry (e.g. a potentiometer to drive the 0 - 10 V input) providing a maximum current of 10 mA. A very high power factor and high efficiency are obtained thanks to the HVLED001 features. Input voltage variations, excessive input voltage (overvoltage such as surges or bursts) or very low input voltages are managed by the HVLED001's protection features, improving the reliability of the application. Output open-circuit and overload protection are autorestarted for safe operation in lighting environments.
