2.3.2 Changing the Phase Configuration

There are two possible phase configurations as shown in Table 3-10. The phase configuration of the EVM must match the phase configuration of the PMIC. Jumper J5 is located on the top side of the PCB, whereas the resistors R1-R3 are on the bottom side of the PCB.

Table 2-10 Phase Configurations
Phase Configuration R1 R2/R3 J5
1(1+1+1+1) R1 R3 N
2(2+1+1) R1 R2 Y

This table is also printed on the EVM on the bottom side of the PCB. All the feedback voltages can be measured from J3, J4, J7, J8 and J15 where J4 is a differential feedback.

Note: A possibility is to use the unused feedback of the secondary buck for voltage monitoring. 0 ohm resistor R2 connecting the FB pin to GND must be opened in this case.
