Latest micropower management unit introduced with seven digital isolators

Analog Devices’ ADP1031 is a high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regulator, an inverting dc-to-dc regulator, and a buck dc-to-dc regulator, providing three isolated power rails. Additionally, the ADP1031 contains four, high speed, serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel-to-channel applications where low power dissipation and a small solution size are required.

Key Features:

  • Wide input supply voltage range: 4.5 V to 60 V
  • Integrated flyback power
  • Generates isolated, independent bipolar outputs and factory programmable buck output
  • VOUT1: 21 V, 24 V, or 6 V to 28 V
  • VOUT2: 5.15 V, 5.0 V, or 3.3 V
  • VOUT3: −24 V to −5 V


  • Industrial automation and process control
  • Instrumentation and data acquisition systems
  • Data and power isolation
