LT3744 Demo Board | Sync Buck LED Driver, 5.5V ≤ VIN ≤ 24V, Drives 3 LEDs @ up to 20A Each

Analog Devices Inc.

Demonstration circuit 2339A is a high current synchronous step-down LED driver featuring the LT3744. The unique drive stage used on the LT3744 allows the anodes of three LEDs to be connected together for better heat sinking in both the step-down configuration and the inverting buck-boost configuration (shown in a separate demonstration circuit DC1930A). The pros and cons of each configuration can be found in the data sheet.  The DC2339A targets high power LEDs and laser diodes (not included). The 3 LEDs are driven from the same output, but each LED is individually controlled. The input voltage range is 5.5V to 30V.
