ADP5033ACBZ-8-R7

Overview

The ADP5033ACBZ-8-R7 is a power management integrated circuit from Analog Devices, classified as a switching voltage regulator. It features four outputs: two synchronous buck regulators capable of delivering up to 800 mA each and two low-dropout (LDO) regulators providing up to 300 mA each. The device operates within an input voltage range of 2.3 V to 5.5 V and supports fixed output voltages including 1.2 V, 1.8 V, 2.8 V, and 3.3 V. It functions reliably across a temperature range of -40°C to +125°C and utilizes a WLCSP-16 package.

Feature Summary

• Integrates dual high-current buck converters and dual LDOs for comprehensive power distribution
• Supports wide input voltage range suitable for single-cell lithium-ion battery applications
• Includes shutdown control capability for enhanced power efficiency management

Applications

• Portable electronic devices requiring multi-rail power supplies
• Battery-powered systems with single-cell lithium-ion inputs
• Embedded applications needing compact power management solutions

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct output voltage settings and package type. Confirm availability status through authorized distributors as supply levels may vary. Ensure compliance with RoHS directives and check for any regional sales restrictions before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is required for powering multiple logic and analog rails from a single cell. The integrated buck and LDO topology reduces external component count compared to discrete designs. Evaluate thermal performance requirements given the high current capabilities in a small form factor package.

Part Context

This part belongs to the ADP5033 family of power management ICs designed for portable electronics. It consolidates multiple regulation stages into a single chip to save board space. The CBZ suffix indicates the WLCSP-16 package variant, distinguishing it from other pinouts or packages in the same series.

Replacement Considerations

Check Analog Devices datasheets for alternative parts within the ADP5033 series that may offer different output configurations or package options. Verify pin compatibility and electrical specifications before substituting with similar PMICs from other manufacturers.
