ADP5034AREZ

Overview

The ADP5034AREZ-1-R7 is a high-integration power management IC featuring four buck regulators and two LDOs. It operates with an input voltage range of 2.3 V to 5.5 V. The device provides two adjustable outputs at 1.2 A, two adjustable outputs at 300 mA, and supports a switching frequency of 3 MHz. It utilizes a 28-TSSOP package with exposed pad and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four synchronous buck converters and two low-dropout linear regulators in a single compact package.
• Features dedicated enable pins for each regulator channel to allow independent control and power sequencing.
• Supports forced PWM mode operation via the MODE pin to minimize output voltage ripple during light loads.

Applications

• Processor system power management
• ASIC and FPGA multi-voltage supply applications
• RF chipset power distribution
• USB-powered portable devices

Procurement Notes

Verify the specific suffix (e.g., -1-R7) against the official Analog Devices datasheet to confirm exact electrical characteristics and pin configuration. Ensure the selected variant matches the required output current ratings and enable pin logic levels for the target application design.

Selection Notes

Select this component when designing systems requiring multiple regulated rails from a single input source. Consider the 3 MHz switching frequency for minimizing external passive component size. Verify that the thermal performance of the 28-TSSOP package meets the requirements for the intended operating environment and load conditions.

Part Context

This part belongs to the ADP5034 series of flexible, high-integration power management devices. It is designed to replace discrete solutions by combining multiple DC-DC and LDO regulators into one chip, reducing board space and simplifying the bill of materials for complex electronic systems.

Replacement Considerations

Check the ADP5034ACPZ-R7 for alternative packaging options. Verify compatibility with existing PCB footprints and ensure that any substitute maintains the same regulatory topology and output capabilities.
