The MAX20078 evaluation kit (EV kit) provides a proven design to evaluate the MAX20078 synchronous buck controller for high-power, high-brightness (HB) LED drivers. The EV kit is set up as a buck LED driver and operates from a 4.5V to 65V DC supply voltage. The EV kit is configured to deliver up to 2A to one string of LEDs. The total voltage of the string can vary from 3V to 55V. The anode of the LED string should be connected to the LED+ terminal and the cathode of the LED string connected to PGND.
