Analog Devices Inc. ADP1031 Micropower Management Units
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.
The ADP1031 micro-PMUs operate at a 4.5V to 60V input voltage range and -40°C to 125°C temperature range. The modules are available in 9mm x 7mm, 41-lead LFCSP package, offering a small solution size. The ADP1031 micropower management units are ideal for channel-to-channel applications. Typical applications include industrial automation, process control, instrumentation, and data acquisition systems.
