ADP5071ACPZ

Overview

The ADP5071ACPZ is a dual-channel 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 independent adjustable outputs ranging from 2.85 V to 39 V. The device delivers up to 1.2 A on the first channel and 2 A on the second channel. It supports boost and SEPIC topologies for generating positive and negative dual rails. The component features a switch frequency of 2.4 MHz and functions within a junction temperature range of -40 °C to 125 °C.

Feature Summary

• Generates independent positive and negative dual voltage rails suitable for bipolar applications
• Integrates boost and SEPIC converter topologies within a single compact package
• Supports high output currents of up to 2 A across dual channels

Applications

• Powering bipolar analog-to-digital converters (ADCs)
• Supplying digital-to-analog converters (DACs)
• Driving operational amplifiers requiring dual polarity supplies

Procurement Notes

Verify that the specific suffix matches the required packaging configuration, as tape-and-reel variants exist alongside tray options. Confirm RoHS compliance status and lead-free characteristics against current manufacturing standards. Ensure the selected variant aligns with the intended assembly process and supply chain requirements for the project.

Selection Notes

Select this component when designing systems requiring simultaneous positive and negative power rails from a single low-voltage source. It is appropriate for space-constrained designs needing high efficiency at 2.4 MHz switching frequencies. Consider the thermal performance in the LFCSP-20 package relative to the expected load current and ambient conditions.

Part Context

This part belongs to the ADP507x series of uPMU regulators designed for IoT and intelligence applications. It complements other Analog Devices data converters by providing simplified dual-rail power solutions. The series aims to reduce design complexity by eliminating the need for multiple discrete power stages or complex routing of high-voltage rails.

Replacement Considerations

The ADP5070 is a related family member offering similar dual-channel regulation capabilities. Verify pinout compatibility and electrical parameter alignment before substitution. Check datasheet specifications for any differences in output current ratings or topology support between the specific model and potential alternatives.
