ADP5076ACBZ-R7

Overview

The ADP5076ACBZ-R7 is a dual-output switching voltage regulator from Analog Devices, designed for applications requiring both positive and negative supply rails. It integrates a boost converter and an inverting topology within a WLCSP-20 package. The device operates with an input voltage range of 2.85 V to 5.5 V. It provides a maximum output current of 2 A at a fixed 35 V output. The component features a switch frequency of 2.4 MHz and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates boost and inverting topologies for simultaneous positive and negative rail generation
• Supports high output current capability up to 2 A
• Operates with low input voltage ranges suitable for single-cell battery systems
• Includes shutdown functionality for power management

Applications

• Powering bipolar analog-to-digital converters (ADCs)
• Supplying negative rails for digital-to-analog converters (DACs)
• Biasing operational amplifiers requiring dual polarity supplies

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the ACBZ variant matches the required WLCSP-20 footprint and thermal characteristics. Ensure the 35 V fixed output aligns with system requirements as adjustable versions may differ. Check for availability constraints as distribution status may vary by region.

Selection Notes

Select this component when a compact solution is needed for generating dual polarities from a low-voltage source. The 2.4 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 2 A current rating meets the peak load demands of the connected analog circuitry.

Part Context

This part belongs to the ADP507x series of ultra-low noise power management ICs. It is distinct from the ADP5073, which offers only a single inverting output, and the ADP5070, which uses a TSSOP-EP-20 package instead of WLCSP. The series targets precision analog applications requiring clean power rails.
