Analog Devices ADP1031 Micropower Management Units (PMUs) are isolated PMUs that offer high performance. These PMUs integrate an isolated flyback DC-to-DC regulator, an inverting DC-to-DC regulator, and a buck DC-to-DC regulator to provide three isolated power rails. These regulators are relatively phase-shifted to one another, resulting in reduced electromagnetic interference (EMI). The ADP1031 µPMUs feature four high-speed serial peripheral interface (SPI) isolation channels and three general-purpose digital isolators. These digital isolators are based on Analog Devices iCoupler® chip-scale transformer technology, optimized for low power and low radiated transmissions.
