ACT88325VA105SR

Overview

The ACT88325VA105SR is a specialized Power Management IC (PMIC) manufactured by Qorvo. It integrates three buck converters, two low-dropout regulators (LDOs), and a load bypass switch within a single package. The device operates with an input voltage range of 2.7 V to 5.5 V. It supports output voltages ranging from 600 mV to 4 V and provides an output current capability of 300 mA. The component is housed in a WLCSP-36 package and is designed for surface-mount installation.

Feature Summary

• Integrates multiple power regulation stages including buck converters and LDOs
• Includes a load bypass switch for direct power path management
• Supports wide input voltage ranges suitable for battery-powered systems

Applications

• Advanced portable electronic devices requiring compact power solutions
• Systems utilizing multi-rail power distribution architectures
• Battery-operated equipment needing efficient voltage regulation

Procurement Notes

Verify the specific suffix and package type against official Qorvo documentation before procurement. Confirm availability status as certain variants may be subject to production changes or end-of-life notices. Ensure compatibility with existing board designs regarding thermal requirements and pin configurations. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this PMIC when a compact solution integrating multiple regulator types is required. Consider the WLCSP-36 package size constraints during layout design. Evaluate the 300 mA output current limit against system peak loads. Verify that the 2.7 V to 5.5 V input range matches the source power supply characteristics. Compare integration benefits against discrete component alternatives for space savings.

Part Context

This component belongs to Qorvo's advanced PMIC family, which consolidates various power management functions into small form factors. These integrated circuits are typically used in mobile and handheld devices where space efficiency and power density are critical. The series offers configurable outputs to meet diverse system voltage requirements while maintaining high efficiency.

Replacement Considerations

Check for updated revisions within the ACT88325 series. Verify if alternative packages such as VA110 or VA120 offer compatible pinouts. Consult Qorvo for officially confirmed substitute part numbers before implementation.
