Key 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

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.
