QUICK START PROCEDURE

Evaluation board EVAL-LTM4702-AZ is easy to set up to
evaluate the performance of the LTM4702. See Figure 1
for the proper measurement equipment setup and follow
the procedure below.
1. With power off, connect the input power supply to V
(4V to 16V) and GND (input return).
2. Connect the 1V output load between V
(Initial load: no load).
3. Connect the DVMs to the input and output. Set default
jumper position:

4. Turn on the input power supply and check for the

5. Once the proper output voltage is established, adjust
the load within the operating range and observe
the output voltage regulation, efficiency, and
IN
other parameters.
NOTE: When measuring the output or input voltage rip-
ple, do not use the long ground lead on the oscilloscope
probe. See Figure 2 for the proper scope probe technique.
Short, stiff leads may be soldered to the (+) and (–) ter-
minals of an output capacitor. The probe's ground ring
needs to touch the (–) lead, and the probe tip needs to
touch the (+) lead.
