Description
- DC2339A, LT3744 Demo Board, Triple LED Driver with a 5.5V to 24V input to 3 outputs up to 20A/each at 5V. The 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. This connection will work in both the step-down configuration and the inverting buck-boost configuration. The pros and cons of each configuration can be found in the data sheet. This demonstration circuit 2339A is for customers to test the step-down configuration only. The inverting buck-boost configuration is shown in a separate demonstration circuit
