5 Address and VSET Resistor
5.1 Adjustment of address resistor
• 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.
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.
6 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.
