STEVAL-ILL072V1
Single channel, 1 A automotive LED driver with boost controller
for interior/exterior lights based on the ALED6001
Data brief
Description
The purpose of this evaluation board is to provide
an application example of a single-channel, highcurrent 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.
Features
Wide DC input voltage (8 V - 24 V)
Single channel, 1000 mA constant-current
output with PWM brightness control
500 kHz switching frequency
Up to 10 high-brightness white LEDs (40 V
OVP threshold)
High efficiency (92% @ Vin = 12 V, Vout = 32
V, Iout = 1 A)
All automotive grade components
RoHS compliant
