4.2 Changing the Phase Configuration

As shown in Figure 4-3, there are five possible phase configurations. It is important that the phase configuration of the EVM matches the phase configuration of the PMIC. Specific consideration should be given to BUCK3 and BUCK4 in phase configurations 1 and 2, since these regulators have independent feedback circuits which can be configured to measure external supplies. FB_B3 and FB_B4 are made available on test points TP6 and TP7 respectively. If the voltage monitors associated with BUCK3 and BUCK4 are disabled, then it is recommended to connect the FB_Bn pins to reference ground, using R4 and R6.
