Power Architecture

ATWINC1500B uses an innovative power architecture to eliminate the need for external regulators and reduce

the number of off-chip components. This architecture is shown in Figure 9-1. The Power Management Unit

(PMU) has a DC/DC Converter that converts VBATT to the core supply used by the digital and RF/AMS blocks.

Table 9-1 shows the typical values for the digital and RF/AMS core voltages. The PA and eFuse are supplied

by dedicated LDOs, and the VCO is supplied by a separate LDO structure.
