ADP5034ACPZ-2-R7

Overview

The ADP5034ACPZ-2-R7 is a high-integration power management IC from Analog Devices, featuring four synchronous buck regulators and two low-dropout (LDO) linear regulators within a single package. It operates with an input voltage range of 2.3 V to 5.5 V and delivers output currents of up to 1.2 A for the buck converters and 300 mA for the LDOs. The device utilizes a 3 MHz switching frequency to minimize external component size and is housed in a 24-pin LFCSP EP package. It supports adjustable outputs via external resistors and includes UVLO features.

Feature Summary

• Integrates four synchronous buck regulators and two LDOs for comprehensive multi-rail power management
• Supports adjustable output voltages using external resistor divider networks for flexible configuration
• Features dedicated enable pins for each regulator channel to allow independent control and sequencing

Applications

• USB-powered portable electronic devices
• Handheld medical instrumentation systems
• Multi-voltage power supplies for processors, ASICs, and FPGAs
• RF chipset power distribution architectures

Procurement Notes

Verify current availability status as supply may be limited or restricted. Confirm that the suffix '2' corresponds to the specific UVLO threshold requirements for your design. Ensure compatibility with the LFCSP-24 footprint and thermal pad soldering specifications during assembly planning.

Selection Notes

Select this component when a compact solution is required for multiple voltage rails from a single 2.3 V to 5.5 V source. It is suitable for designs needing both high-efficiency switching regulation and low-noise LDO outputs. Verify that the 3 MHz switching frequency aligns with EMI constraints and inductor size limitations.

Part Context

This part belongs to the ADP5034 family of power management ICs, which are designed for high integration in space-constrained applications. The series combines switching regulators and LDOs to reduce board area and simplify power architecture for complex digital systems requiring multiple stable voltage levels.

Replacement Considerations

Check for ADP5034ACPZ-R7 if a different UVLO configuration is acceptable. Evaluate ADP5024 variants for similar functionality with potential pinout differences. Always verify datasheet revisions and electrical parameter tolerances before substituting.
