STEVAL-ILL078V1

Evaluation board is based on the LED6000 monolithic current source for high power LED driving. Digital dimming is implemented by driving the dedicated DIM pin. Low drop-out operation with almost 100% duty cycle can be achieved. The LED6000is a 61 V asynchronous switching regulator with embedded power MOSFET, designed to source up to 3 A of DC current depending on the application conditions. The 250mV typical RSENSE voltage drop, the embedded switch-over feature on the VBIAS pin and light load management (pulse skipping) are intended to maximize power conversion efficiency across the entire load range.
