ACT88321VU112SR

Overview

The ACT88321VU112SR is a specialized Power Management IC (PMIC) manufactured by Qorvo. It integrates three buck converters, two low-dropout regulators (LDOs), and load bypass switches within a WLCSP-30 package. The device supports an input voltage range of 2.7 V to 5.5 V and delivers up to 4 A output current. Maximum output voltage reaches 3.775 V, with an operating temperature range from -40°C to +150°C.

Feature Summary

• Integrates multiple power stages including three buck converters and two LDOs for comprehensive voltage regulation.
• Includes load bypass switches to manage power delivery paths efficiently.
• Designed for high-temperature operation suitable for demanding industrial or automotive environments.

Applications

• Video processors
• FPGAs
• Microcontrollers

Procurement Notes

Verify the specific suffix 'VU112' against official Qorvo documentation to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with WLCSP-30 assembly processes. Confirm availability through authorized distributors as supply status may vary.

Selection Notes

Select this PMIC when a compact solution is required for systems needing multiple regulated rails from a single wide-input voltage source. The high maximum operating temperature of 150°C makes it suitable for applications exceeding standard commercial limits. Verify that the 4 A current capability meets the peak load demands of the target processor or FPGA.

Part Context

This component belongs to Qorvo's Advanced PMIC family, designed for complex system-on-chip power architectures. It replaces discrete power solutions by consolidating buck, LDO, and switching functions into a single small-footprint package, reducing board space and component count in high-density designs.

Replacement Considerations

Check Qorvo datasheets for direct pin-to-pin compatible alternatives within the ACT8832x series. Verify if variants like ACT88329 offer similar integration but different voltage ranges or current capabilities suitable for your specific application constraints.
