Description
General part information
STEVAL-LLL014V1 Series
The STEVAL-LLL014V1 is a four LEDs strings evaluation kit based on the ALED7709 LED driver configured in boost.
The ALED7709 is an automotive LED driver (AEC-Q100 Grade1 qualified), it includes a DC/DC controller usable as boost or SEPIC, and four low-side constant-current sinks.
The integration of the boost controller with the LED sinks, gives the possibility of adapting the boost voltage for the different LED conditions, minimizing the power dissipation in the ALED7709 and as consequence increasing the overall efficiency.
