ACT88329VU101SR

Overview

The Qorvo ACT88329VU101SR is a specialized Power Management IC (PMIC) designed for high-performance applications. It integrates three buck converters, two LDOs, and a load bypass switch within a compact WLCSP-30 package. The device supports an input voltage range of 2.7 V to 5.5 V and operates across a temperature range of -40°C to +125°C. Key electrical specifications include a maximum output current of 4 A for the primary buck regulators and a quiescent current of 260 uA. The part utilizes a 1 MHz I2C interface for configuration and features seven programmable GPIOs.

Feature Summary

• Integrates three DC/DC buck regulators, two low-dropout linear regulators, and a load bypass switch into a single compact package.
• Offers extensive configurability via a microprocessor interface, allowing real-time adjustment of output voltages, sequencing, and switching frequencies without hardware changes.
• Includes seven programmable general-purpose input/output pins and multiple wake-up triggers for flexible system control.
• Supports various sleep modes and provides status reporting through power-good and reset GPIO signals.

Applications

• Solid-State Drives (SSD)
• Field-Programmable Gate Arrays (FPGA)
• Computer Vision Systems
• Portable Audio and Video Devices

Procurement Notes

Verify the specific suffix 'VU101SR' against the manufacturer's official documentation to confirm pinout compatibility and internal configuration settings. Ensure that the procurement source provides valid traceability data consistent with Qorvo's quality standards. Cross-reference the component marking with the datasheet to prevent substitution errors during assembly.

Selection Notes

Select this PMIC when a highly integrated solution is required to minimize PCB area and external component count. It is suitable for designs needing flexible power sequencing and real-time reconfiguration capabilities. Consider its thermal performance in the WLCSP-30 package relative to the expected load currents and ambient operating conditions.
