The STEVAL-ILL070V4 is intended to drive one 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 (for example, provided by a microcontroller) on the SELV portion of the board. The universal input capability makes this board suitable in worldwide designs. On the secondary side, the board includes a connector to plug an auxiliary linear on the switching voltage regulator side to supply small circuits (e.g., IoT wireless expansions like BLE, Spirit or WiFi modules). The schematic for a simple linear regulator to supply 5 V or 3.3 V is also provided. A very high power factor and efficiency are obtained even at light loads.
