ADP5071ACPZ-R7

Overview

The ADP5071ACPZ-R7 is a dual-output DC-DC switching regulator from Analog Devices, housed in a 20-pin LFCSP package. It operates with an input voltage range of 2.85 V to 15 V and provides two adjustable outputs capable of delivering up to 1.2 A and 2 A respectively. The device supports boost and SEPIC topologies to generate positive and negative rails, with output voltages adjustable from 0.8 V/1.6 V up to ±39 V. It features switchable frequencies of 1.2 MHz or 2.4 MHz and functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Generates independent positive and negative supply rails from a single low-voltage source
• Integrates dual synchronous rectifiers for high efficiency across load ranges
• Offers selectable switching frequencies to optimize external component size and performance

Applications

• Powering bipolar analog-to-digital converters (ADCs) and digital-to-analog converters (DACs)
• Supplying operational amplifiers requiring dual polarity power
• Providing bias voltages for precision sensor interfaces

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and pinout compatibility. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a compact solution is needed to derive dual polarities from a single rail. Consider the maximum current requirements of both channels and the desired switching frequency to determine appropriate external passive components.

Part Context

This part belongs to the ADP507x family of uPMU regulators designed for space-constrained applications. It serves as a specialized power management IC for systems requiring clean, regulated dual supplies without complex transformer-based designs.

Replacement Considerations

The ADP5070 is a related device within the same family; verify functional equivalence and pinout compatibility before substitution.
