7.2 Configure Channel 2 and Channel 3 as a Dual Phase Buck Controller

Section 7.2 describes how to configure channel 2 and channel 3 as a dual phase interleaved buck controller. Figure 7-2 and Figure 7-3 show the typical applications when channel 2 and channel 3 is configured as a dual phase buck controller.
