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.
