Single Channel, 1 A Automotive LED Driver with Boost Controller for Interior/exterior Lights Evaluation Board based on the ALED6001
Manufactured By:ST Microelectronics
Part Number:STEVAL-ILL072V1
The purpose of this evaluation board is to provide an application example of a single-channel, high-current LED driver using the ALED6001 chip operating with a boost topology. The brightness of the LED string connected to its output can be controlled through a PWM signal (0% - 100% dimming) or a control voltage (10:1 analog dimming). Open LED, feedback disconnection & LED overcurrent fault conditions are detected and managed.
The evaluation board has been designed to provide an example of a compact solution for all automotive applications involving several LEDs arranged is a single string, and day-time running lights (DTRL) in particular.
