ACT88321VU104SR

Overview

The Qorvo ACT88321VU104SR is an advanced processor power management IC (PMIC) designed for high-performance applications. It integrates three buck converters, two low-dropout (LDO) regulators, and a load bypass switch within a single compact package. The device operates with an input voltage range of 2.7 V to 5.5 V and supports output currents up to 4 A. It features a maximum operating temperature of +150 °C and a minimum of -40 °C. The unit is housed in a WLCSP-30 package, measuring approximately 2.18 x 2.58 mm, suitable for space-constrained designs.

Feature Summary

• Integrates multiple power stages including three synchronous buck converters and two LDOs for comprehensive voltage regulation.
• Includes a load bypass switch to ensure continuous power delivery during specific operational states or faults.
• Engineered for high thermal performance with extended operating temperature ranges up to +150 °C.
• Utilizes a wafer-level chip-scale package (WLCSP) to minimize footprint and simplify PCB layout.

Applications

• High-end mobile processors requiring multi-rail power sequencing
• Advanced communication baseband units
• Portable computing devices with strict size constraints

Procurement Notes

Verify the exact suffix configuration against official Qorvo documentation to ensure correct voltage settings and package variants. Confirm availability through authorized distributors as stock levels may vary. Ensure compatibility with your system's input voltage and thermal requirements before integration.

Selection Notes

Select this PMIC when a compact solution is needed for powering complex processor systems. The integrated buck and LDO combination reduces component count. Verify that the 4 A current capability meets the peak load demands of the target application. Consider the WLCSP-30 package size relative to available board space.
