ACT88325VA118-T

Overview

The ACT88325VA118-T is a specialized Power Management Integrated Circuit (PMIC) manufactured by Qorvo. It functions as an ActivePMU™ unit designed for flexible system power management without requiring PCB changes. The device integrates three DC/DC buck converters and two Low Dropout (LDO) regulators, all configurable via an I2C interface. This architecture supports various application processor configurations while minimizing external component count.

Feature Summary

• Integrates three high-efficiency DC/DC buck converters and two LDO regulators within a single package.
• Features full configurability through an I2C serial interface for output voltage, sequencing, and operating modes.
• Includes integrated load bypass switches to optimize system-level power routing and efficiency.
• Utilizes a compact 36-ball WLCSP package with optimized pinout for efficient PCB layout.

Applications

• Application processors from manufacturers such as Silicon Motion, Ambarella, Atmel, Micro Semi, Socionext, and Omnivision
• Portable audio and video devices
• Wearable electronics

Procurement Notes

Verify the specific suffix 'VA118' against official Qorvo documentation to confirm exact factory default configurations. Confirm availability status as supply may be limited or subject to special ordering protocols. Ensure compatibility with existing I2C bus designs and validate thermal performance within the specified WLCSP footprint before finalizing procurement decisions.

Selection Notes

Select this PMIC when designing systems requiring high flexibility in power rail configuration without hardware redesigns. It is suitable for applications needing multiple regulated outputs from a single IC to reduce board space. Consider its I2C programmability for optimizing startup sequences and sleep modes tailored to specific processor requirements.

Part Context

This component belongs to the ACT88325 series of Advanced PMICs from Qorvo. The series is characterized by its ActivePMU technology, which allows extensive reconfiguration via software. Other variants in the family share similar core architectures but differ in packaging, default settings, or specific integration levels.

Replacement Considerations

Direct substitutes include other ACT88325 series variants such as ACT88325VA110-T or ACT88325VA117SR. Verify that the alternative part number matches the required pinout and default voltage settings to ensure seamless integration into the existing design.
