The step-down converters SMPS1, SMPS2, and SMPS3 can be used in two different configurations:
SMPS1 and SMPS2 cannot be used as separate converters. In dual-phase configuration the two interleaved synchronous buck regulator phases with built-in current sharing operate in opposite phase. In triple-phase configuration the three interleaved synchronous buck regulator phases with built-in current sharing operate 120° out of phase. For light loads, the converter automatically changes to 1-phase operation.
Figure 6-6 shows the connections for dual-phase and triple-phase configurations.
To use the SMPS123 or SMPS12 and SMPS3 in the system:
