The MSP432P401x MCUs can be programmed to operate either with an LDO or with a DC-DC as the voltage regulator for the digital logic in the core domain of the device. The DC-DC offers significant boost in power efficiency for high-current high-performance applications. The LDO is a highly efficient regulator that offers power advantages at lower VCC ranges and in the ultra-low-power modes of operation.
The core operating voltage (output of the LDO or DC-DC) is automatically set by the device depending on the selected operating mode of the device (see Table 6-42 for further details). The device offers seamless switching between LDO and DC-DC operating modes and also implements a seamless DC-DC fail-safe mechanism.
