QUICK START PROCEDURE
Demonstration circuit 1379A is easy to set up to evaluate
the performance of the LTM8025. Refer to Figure 1 for
proper measurement equipment set-up and follow the
procedure below:
NOTE. When measuring the input or output voltage ripple,
care must be taken to avoid a long ground lead on the
oscilloscope probe. Measure the input or output voltage
ripple by touching the probe tip directly across the V
or V
scope probe technique.
1. Place JP1 on the ON position.
2. Preset the power supply within the input voltage range

output voltage regulation, ripple voltage, efficiency and
other parameters.
JP2 is in the SYNC ON position. See the synchronization
section in the data sheet for details.
