DEMO MANUAL DC2242A
Quick start proceDure
DC2242A is easy to set up to evaluate the performance
of the LT8494. Refer to Figure 3 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 V
or V
and GND terminals. See Figure 4 for the proper
OUT
scope technique.
1. With power off, connect the input power supply to V
and GND. Make sure that the input voltage does not
exceed 60V.

2. With power off, connect loads from V
3. Turn on the power at the input.
4. Check for the proper output voltages (V
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 load within the operating ranges and observe the
output voltage regulation, ripple voltage, efficiency and

other parameters.
