STEVAL-ILL084V1

Evaluation board is based on the LED6000 monolithic current source for high power LED driving. The floating boost topology can benefit from the LED6000 wide input voltage range to drive many power LED in series. The LED6000 is a 61V asynchronous switching regulator with embedded power MOSFET, designed to supply up to 3A DC currents depending on the application conditions. The 250 mV typical RSENSE voltage drop, embedded switch-over feature on the VBIAS pin and light load management (pulse skipping) maximize power conversion efficiency across the entire load range. Digital dimming is implemented by driving the dedicated DIM pin.
