10.4.4.5.3 SW3A – SW3B independent outputs
SW3A and SW3B can be configured as independent outputs as shown in Figure 22,
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 64.
