DEMO MANUAL DC1723A
QUICK START PROCEDURE
Demonstration circuit 1723A is easy to set up to evalu-
ate the performance of the LTM8050. Refer to Figure 1
for proper measurement equipment setup 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 terminals
of the input or output capacitors. See Figure 2 for proper
scope probe technique.
1. Place JP1 in the ON position.
2. With power off, connect the input power supply to VIN
and GND.
3. Turn on the power at the input.

Note: Make sure that the input voltage does not exceed 58V.
4. Check for the proper output voltage.
Note: If there is no output, temporarily disconnect the load
to make sure that the load is not set too high or is shorted.
5. Once the proper output voltage is established, adjust
the loads within the operating range and observe the
output voltage regulation, ripple voltage, efficiency and
other parameters.
