Description
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.
