DEMO MANUAL SCP-LT3094-EVALZ

QUICK START PROCEDURE

Demonstration circuit SCP-LT3094-EVALZ is easy to set
up to evaluate the performance of any SCP hardware
configuration.
1. The SCP-LT3094-EVALZ ships with a default output
voltage of –3.3V. 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-LT3094-EVALZ (refer to Fig-
ure 2) and connect the input board to a voltage source,
V . Connect the output board to a voltmeter or
SOURCE
dynamic load. Slowly raise the input voltage until the
SCP-LT3094-EVALZ powers up into regulation and
sweep V through the desired range of operation.

NOTE: Make sure that the input voltage is always within
spec. If using a dynamic load to measure output volt-
age, 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.
