5.2

Adjustment of VSET resistors

Populate a jumper in each "Vset" position to get the desired output voltage. The
silk screen marking shows the voltage settings that can be achieved by populating
jumpers.

Test points

Input voltage should be measured at test points VIN/GND, which are
connected directly to the VIN / GND pin of the module.
Output voltage should be measured at test points VO/GND, which are
connected directly to the VO/GND pin of the module.

To change the address, change the resistor shown in Figure 2. Change R4
and R5 (position 11) to achieve the desired PMBus address for the
module.
Refer to chapter 'PMBus addressing' in the technical specification to select
the proper values.
Figure 2 Address resistor position, R4 and R5, is shown in the picture.
