DEMO MANUAL DC2001A

Quick start proceDure

Demonstration circuit 2001A is easy to set up to evalu-
ate the performance of the LTC3787. Refer to Figure 1
for proper measurement equipment setup and follow the
procedure below.
1. Set the jumper as follows:
JP1: FCC
JP2: ON
2. With all power off, connect the input power supply,
load, and meters using heavy duty cables, as shown in
Figure 1.
NOTE: Input supply must be capable of at least 65A at
12V, or 110A at 6V.
3. Preset the system load to 0A and the input supply to
12V, 2A current limit.

4. Turn on the supply and adjust the voltage to the desired
5. Once the proper output voltage has been established,
6. Turn on the load and adjust as necessary.
Optional
1. For pulse skip or Burst Mode
2. To shut down switching, set jumper JP2 to OFF.
3. For power good indication, monitor PGOOD.
4. For external clock synchronization, connect the clock
