Functional Block Requirements and Behaviors
Power Generation
SW1A/B/C Single Phase
In this configuration, all phases A, B, and C, are connected together to a single inductor, thus, providing up to 4.50 A current
capability for high current applications. The feedback and all other controls are accomplished by use of pin SW1CFB and SW1C
control registers, respectively. Figure 10 shows the connection for SW1A/B/C in single phase mode.
During Single Phase mode operation, all three phases will use the same configuration for frequency, phase, and DVS speed set
in SW1CCONF register. However, the same configuration settings for frequency, phase, and DVS speed setting on SW1AB
registers should be used. The SW1FB pin should be left floating in this configuration.
