1 / 4 page June 2015 DocID027966 Rev 1 1/4 For further information contact your local STMicroelectronics sales office www.st.com STEVAL-ILL072V1 Single channel, 1 A automotive LED driver with boost controller for interior/exterior lights Data brief 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) RoHS compliant All automotive grade components 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. |
