QUICK START PROCEDURE

Demonstration circuit 2830A makes it easy to use the
LTC7106 to adjust the LTM4636 output voltage. This
demo manual will focus on the evaluation of LTC7106.
For the LTM4636 evaluation procedure, please refer to the
DC2230A-A demo manual on the Analog Devices website.
Please refer to Figure 1 for proper demo board setup with
PC and follow the procedure below:

STEP
1. Place jumpers in the following positions for a typical
application:
MODE (JP2)
CCM
2. With power off, connect the input power supply, load
and meters as shown in Figure 1. Preset the load to 0A
and V supply to 12V.

3. Turn on the power supply at the input. The output volt-
age should be 1.0V ±2.3% (0.977V to 1.023V).
4. Vary the input voltage from 6V to 15V and adjust the
load current from 0A to 40A. Observe the output volt-
age regulation, ripple voltage, efficiency, and other
parameters.
5. Once the proper output voltage is established on the
LTM4636 output, put JP5 to the ON position to enable
the LTC7106.
