ACT88325VA120SR

Overview

The ACT88325VA120SR is a specialized Power Management Integrated Circuit (PMIC) manufactured by Qorvo. It integrates three buck converters, two Low Dropout (LDO) regulators, and a load bypass switch within a single package. This component is designed to provide efficient power distribution for complex digital systems requiring multiple voltage rails.

Feature Summary

• Integrates three independent buck converters and two LDOs for comprehensive power management
• Includes a load bypass switch to support system-level power sequencing requirements
• Offers configurable operating modes and parameters via an I2C interface

Applications

• Solid State Drive (SSD) controller power supplies
• Field Programmable Gate Array (FPGA) core and I/O power
• Video processor and computer vision system power distribution

Procurement Notes

Verify the specific suffix 'SR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Check for Product Change Notifications (PCN) regarding manufacturing site or material updates. Confirm availability status as some variants may be subject to limited supply or end-of-life transitions.

Selection Notes

Select this PMIC when a compact solution is needed for processors requiring three distinct buck voltages and two LDO outputs. Ensure the input voltage range of 2.7V to 5.5V matches the system bus. Verify that the integrated switching frequency and external inductor values align with the PCB layout constraints and efficiency targets.

Part Context

This part belongs to the Qorvo ACT88325 series of advanced PMICs. It shares functional similarities with the ACT88329 but may differ in specific output configurations or pinouts. The series is optimized for high-density applications such as SSDs and FPGAs where space savings and integration are critical design factors.

Replacement Considerations

Direct substitutes include other ACT88325 variants with different output voltage settings, such as ACT88325VA110-T or ACT88325VA135. Cross-reference pin compatibility and electrical characteristics before replacing. The ACT88329 is a related family member but requires verification of functional equivalence.
