Analog Devices Inc. ADP1034 Micropower Management Unit (PMU)

Analog Devices Inc. ADP1034 Micropower Management Unit (PMU) is a high-performance and isolated PMU that combines an isolated flyback dc-to-dc regulator, buck-boost, and buck dc-to-dc regulator. The ADP1034 PMU has four high-speed Serial Peripheral Interface (SPI) isolation channels and three general-purpose isolators for channel-to-channel applications. This PMU operates at a 4.5V to 60V wide input supply voltage range. The ADP1034 PMU offers 86% of typical efficiency at 2.61W output power. This PMU features high speed, low propagation delay, and SPI signal isolation channels. Applications include industrial automation and process control, instrumentation and data acquisition systems, and data and power isolation.
