产品概述
描述
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 auto-restarted for safe operation in lighting environments.
