DEMO MANUAL DC1831A

QUICK START PROCEDURE

Demonstration circuit 1831A is easy to set up to evalu-

ate the performance of the LT3763. Refer to Figure 2 for

proper measurement equipment setup and follow the

procedure below:

1. With power off, connect the input power supply to VIN

and GND. Note: make sure VIN is below 60V.

2. With power off, connect the LED load to VOUT and

GND (without PWM dimming) or VOUT and LED– (with

PWM dimming).

3. When measuring input and output voltage, measure at

test points TP1 to TP4.

4. Turn on the power at the input.

5. Carefully evaluate other design parameters as needed.
