FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS
6.4.4.5.2
SW3A/B dual phase
SW3A/B can be connected in dual phase configuration using one inductor per switching node, as shown in Figure 18. This mode allows
a smaller output voltage ripple. Feedback is taken from pin SW3AFB and pin SW3BFB must be left open. Although control is from SW3A,
registers of both regulators, SW3A and SW3B, must be identically set. In this configuration, the regulators switch 180 degrees apart.

6.4.4.5.3
SW3A - SW3B independent outputs
SW3A and SW3B can be configured as independent outputs as shown in Figure 19, providing flexibility for applications requiring more
voltage rails with less current capability. Each output is configured and controlled independently by its respective I2C registers as shown
in Table 65.
