ADP1031ACPZ-2

Overview

The ADP1031ACPZ-2 is an isolated ultra-Power Management Unit (uPMU) and digital isolator manufactured by Analog Devices Inc. It integrates a high-voltage DC/DC converter with three isolated outputs within an LFCSP-41 package. The device accepts an input voltage range of 4.5 V to 60 V, supporting a maximum output voltage of 28 V. It provides a regulated 5.0 V output at 300 mA for the secondary side. The unit operates between -40°C and +125°C with a quiescent current of 1.77 mA.

Feature Summary

• Integrates isolated power conversion and digital signal isolation in a single component
• Provides multiple regulated isolated outputs including a dedicated 5.0 V rail
• Supports wide input voltage ranges up to 60 V for industrial applications

Applications

• Industrial control systems requiring galvanic isolation
• Power supply modules with integrated digital communication
• Equipment needing compact isolated power management solutions

Procurement Notes

Verify the specific suffix '-2' against the official Analog Devices datasheet to confirm the exact output configuration and pinout. Ensure the LFCSP-41 package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when a combined solution for isolated power delivery and digital data transmission is required. The integrated nature reduces bill-of-materials count compared to discrete converters and isolators. Verify that the 300 mA output current capability satisfies the load requirements of the downstream circuitry.

Part Context

This part belongs to the ADP1031 series of isolated uPMUs. It is designed to simplify system architecture by combining power and data isolation. The device is distinct from standard regulators due to its integrated transformer driver and digital channel capabilities.

Replacement Considerations
