ADP5022ACBZ-2-R7 Equivalent & Substitute Parts

Part Overview

The ADP5022ACBZ-2-R7 is a Power Management Integrated Circuit (PMIC) manufactured by Analog Devices Inc., classified as a Voltage Regulator with linear switching topology. This device integrates three independent outputs: two synchronous step-down (buck) regulators and one linear (LDO) regulator, operating at a switching frequency of 3MHz. The part is packaged in a 16-WLCSP (2.08x2.08mm) ball grid array format suitable for space-constrained surface mount applications.

The ADP5022ACBZ-2-R7 is currently listed as Obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this PMIC topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADP5022ACBZ-2-R7 is determined by the following critical parameters:

Topology Compatibility: The substitute part must maintain the same functional architecture: two synchronous buck regulators and one linear LDO regulator with three independent outputs.

Switching Frequency: The substitute must operate at 3MHz to maintain equivalent transient response and filtering characteristics in the power delivery network.

Output Configuration: The substitute must provide three independent regulated outputs with voltage and current ratings that meet or exceed the original design specifications.

Supply Voltage Range: The substitute must accept the same input voltage range (2.3V ~ 5.5V) to ensure compatibility with existing power source designs.

Operating Temperature Range: The substitute must support the full industrial temperature range (-40°C ~ 125°C) for equivalent thermal performance.

Package and Mounting: While package form factor may differ, the substitute must be surface-mountable and compatible with standard PCB assembly processes.

The ADP5023ACPZ-2-R7 meets these substitution criteria while offering enhanced output voltage flexibility and higher current ratings on the buck outputs.

Engineering Selection Recommendations

Product Status Consideration: The ADP5022ACBZ-2-R7 is classified as Obsolete, making the ADP5023ACPZ-2-R7 the appropriate substitute. The ADP5023ACPZ-2-R7 maintains Active product status with ongoing manufacturer support and supply availability.

Compliance and Certifications: The ADP5023ACPZ-2-R7 is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components in industrial and consumer applications. Both parts carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Functional Equivalence: The ADP5023ACPZ-2-R7 provides the same three-output topology with identical switching frequency. The substitute offers programmable output voltage ranges on the buck regulators, providing design flexibility beyond the fixed outputs of the original part.

Package Transition: The ADP5023ACPZ-2-R7 uses a larger 24-LFCSP-WQ package (4x4mm) compared to the original 16-WLCSP (2.08x2.08mm). PCB layout modifications are required to accommodate the increased package footprint and pin count.

Frequently Asked Questions (FAQ)

Q: Can the ADP5023ACPZ-2-R7 directly replace the ADP5022ACBZ-2-R7 without design changes?

A: The ADP5023ACPZ-2-R7 provides functional equivalence in topology and switching frequency. However, the larger package footprint (24-LFCSP-WQ versus 16-WLCSP) requires PCB layout redesign. Pin assignments and control signal interfaces must be verified against device datasheets before implementation.

Q: What are the key differences in output specifications between these parts?

A: The ADP5022ACBZ-2-R7 provides fixed output voltages (1.2V/600mA, 1.8V/600mA, 2.8V/150mA). The ADP5023ACPZ-2-R7 offers programmable output voltage ranges (0.8V~3.8V/800mA on outputs 1 and 2; 0.8V~4.75V/300mA on output 3), enabling broader application flexibility.

Q: Are there supply voltage compatibility concerns?

A: The ADP5023ACPZ-2-R7 accepts a lower minimum supply voltage (1.7V versus 2.3V). This expanded range maintains compatibility with existing 2.3V~5.5V power sources while enabling operation in lower-voltage applications.

Q: What is the impact of the different Moisture Sensitivity Levels (MSL)?

A: The ADP5022ACBZ-2-R7 has MSL 1 (Unlimited shelf life). The ADP5023ACPZ-2-R7 has MSL 3 (168-hour floor life after moisture exposure). Storage and handling procedures must comply with MSL 3 requirements to prevent moisture-induced failures during assembly.

Q: Are there other substitute parts available from Analog Devices?

A: The ADP5023ACPZ-2-R7 is the primary substitute listed for the ADP5022ACBZ-2-R7. Additional variants of the ADP5023 series (ADP5023ACPZ-R2, ADP5023ACPZ-R7) exist with different tape reel configurations but identical electrical specifications.
