DEMO MANUAL SCP-LTC3114-1-EVALZ

QUICK START PROCEDURE

Demonstration circuit SCP-LTC3114-1-EVALZ is easy to
set up to evaluate the performance of any SCP hard-
ware configuration.
1. The SCP-LTC3114-1-BB-EVALZ ships with a default
output voltage of 5V. To change the output voltage, see
"Configuration Settings" section, and modify the board
accordingly. Be sure to check for open connections or
solder shorts after making any modifications.
2. Connect the SCP-INPUT-EVALZ and SCP-OUTPUT-
EVALZ boards to the SCP-LTC3114-1-BB-EVALZ (refer
to Figure 2) and connect the input board to a voltage
source, V . Connect the output board to a volt-
SOURCE
meter or dynamic load. Slowly raise the input voltage
until the SCP-LTC3114-1-BB-EVALZ powers up into
regulation and sweep V
range of operation.

SOURCE
NOTE: Make sure that the input voltage is always within
specification. If using a dynamic load to measure out-
put voltage, make sure the load is initially set to zero.
3. Check for proper output voltage. The output should be
regulated at the programmed value (±5%).
4. Once the proper output voltage is established, power
off V and similarly test other boards in the SCP
SOURCE
system until all elements have been individually verified
prior to assembling into the final circuit configuration.
NOTE: When measuring the input or output voltage rip-
ple, use the optional SMA connector locations available
on the input, output, 1 ´ 5, 1 ´ 2, and 5 ´ 1 breakout
boards. Avoid using the test point connections with
long scope leads.
