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).
