ADP1031ACPZ-3-R7

Overview

The ADP1031ACPZ-3-R7 is a high-performance isolated micro-power management unit (PMU) integrating three independent power rails and seven digital isolators. It operates with an input voltage range of 4.5 V to 60 V. The device provides a flyback output (VOUT1) of 21 V or 24 V, a factory-programmable buck output (VOUT2) of 3.3 V, and an inverting output (VOUT3) adjustable from -24 V to -5 V. It includes four SPI isolation channels and three general-purpose isolators.

Feature Summary

• Integrates flyback, buck, and inverting regulators with seven digital isolators
• Optimized for low power consumption and small solution size
• Includes internal compensation and soft-start control for all regulators

Applications

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

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm the exact factory-programmed output voltages for VOUT1 and VOUT2. Confirm package type and thermal specifications match design requirements before procurement.

Selection Notes

Select this component when channel-to-channel isolation is required with minimal footprint. Ensure the application benefits from the integrated digital isolators to reduce external component count. Verify that the fixed output voltages meet system power distribution needs.

Part Context

This part belongs to the ADP1031 series of isolated PMUs. It combines multiple power conversion stages and signal isolation into a single LFCSP-41 package. The series supports various output configurations tailored for industrial applications requiring robust electrical isolation.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully.
