SW1A/B Single Phase - SW1C Independent Mode
In this configuration, SW1A/B is connected as a single phase with a single inductor, while SW1C is used as an independent
output, using its own inductor and configurations parameters. This configuration allows reduced component count by using only
one inductor for SW1A/B. As mentioned before, SW1A/B and SW1C operate independently from one another, thus, they can be
operated with a different voltage set point for Normal, Standby, and Sleep modes, as well as switching mode selection and on/
off control. Figure 11 shows the physical connection for SW1A/B in single phase and SW1C as an independent output.

Figure 11. SW1A/B Single Phase, SW1C Independent Mode Block Diagram
Both SW1ALX and SW1BLX nodes operate at the same DVS, frequency, and phase configured by the SW1ABCONF register,
while SW1CLX node operates independently, using the configuration in the SW1CCONF register.
