4.2 Changing the Phase Configuration
, 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.
