1 A Buck LED Driver Board Based on the ALED6000 Automotive Grade Dimmable

Standards/Approvals

RoHS and WEEE

The STMicroelectronics STEVAL-ILL089V1 evaluation board is based on the ALED6000 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 ALED6000 is a 61 V asynchronous switching regulator with embedded Power MOSFET, designed to source up to 3 ADC current depending on the application conditions. The 250 mV typical RSENSE voltage drop, the embedded switchover feature on the VBIAS pin and the light load management (pulse skipping) all contribute to maximizing power conversion efficiency across the entire load range.
