DEMO MANUAL DC1261A

QUICK START PROCEDURE

Demonstration circuit 1261A is an easy way to evaluate

the performance of the LTM8022. 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 VIN or

VOUT and GND terminals. See Figure 2 for proper scope

probe technique.

1. Place JP1 on the ON position.

2. With power off, preset the input supply within the op-

erating range of the LTM8022 then connect the input

power supply to VIN and GND.

3. Turn on the input power supply.

Note: Make sure that the input voltage does not exceed

the maximum input voltage.

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.

5. Once the proper output voltage are established, adjust

the load within the operating range and observe the

output voltage regulation, ripple voltage, efficiency and

other parameters.
