ACT88325VA135SR

Overview

The ACT88325VA135SR is a specialized Power Management IC (PMIC) from Qorvo. It integrates three DC/DC step-down regulators, two Low Dropout (LDO) regulators, and a high-power load switch gate driver with slew rate control. The device features one 4A buck converter with bypass mode, two 3A buck converters, and two 300mA LDOs. Designed for compact applications, it supports I2C configuration for flexible system-level sequencing and power management.

Feature Summary

• Integrates multiple voltage regulation stages including high-current buck converters and low-noise LDOs within a single package.
• Features a dedicated high-power load switch gate driver with adjustable slew rate control for efficient power delivery.
• Supports flexible system integration through I2C programmable sequencing and configurable operating modes.

Applications

• Solid State Drives (SSD)
• Field Programmable Gate Arrays (FPGA)
• Video processors
• Wearable devices

Procurement Notes

Verify the specific suffix 'SR' against official Qorvo documentation to confirm tape-and-reel packaging specifications. Confirm current lifecycle status as some variants in this series are marked as obsolete or limited supply. Ensure compatibility with existing PCB footprints and I2C addressing schemes before procurement.

Selection Notes

Select this component when a compact solution is required for powering complex digital systems like SSDs or FPGAs. The integrated load switch and configurable sequencing reduce external component count. Verify that the 4A and 3A output currents meet the peak load requirements of the target processor cores.

Part Context

This part belongs to the Qorvo Advanced PMIC family, designed for high-density electronics. It shares architectural similarities with the ACT88329 but offers specific output configurations tailored for storage and computing applications. The WLCSP package minimizes board space usage compared to traditional QFN solutions.

Replacement Considerations

Check for direct pin-to-pin replacements within the ACT88325 series. Verify if the ACT88329 serves as a functional alternative if output current ratings align. Consult Qorvo Product Change Notifications for any manufacturing updates affecting equivalent parts.
