DEMO MANUAL DC1623A
Demonstration circuit DC1623A is an easy way to evalu-
ate the performance of the LTM8033. 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, preset the input power supply within

the operating input voltage range and connect to V
and GND.
IN
3. Turn on the power at the input.
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
6. An external clock can be added to the SYNC pin when
the loads within the operating range and observe the
output voltage regulation, ripple voltage, efficiency and
other parameters.
SYNC function is used. See the Synchronization section
in the data sheet for details.
