Product Overview

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 61V asynchronous switching regulator with embedded Power MOSFET, designed to source up to 3 ADC current depending on the application conditions. The 250mV typical RSENSE voltage drop, the embedded switchover feature on the VBIAS pin and the light load management all contribute to maximizing power conversion efficiency across the entire load range. The current limit threshold and the switching frequency are adjustable for application optimization. The device includes an internal 250KHz oscillator that can be externally adjusted up to 1.5MHz. Two LED6000 regulators can be synchronized in a 180° out-of-phase configuration for reduced total input RMS current.
