ACT88321VU103SR

Overview

The ACT88321VU103SR is a specialized power management IC (PMIC) from Qorvo, designed for advanced multi-channel applications. It integrates three buck converters and two low-dropout regulators (LDOs), along with load bypass switches. The device operates within an input voltage range of 2.7 V to 5.5 V. It supports a maximum output current of 4 A and delivers a maximum output voltage of 3.775 V. The component functions reliably across a wide temperature range, from -40 °C to +150 °C. It is housed in a WLCSP-30 package suitable for surface mount technology.

Feature Summary

• Integrates multiple regulation stages including three buck converters and two LDOs within a single compact package.
• Includes integrated load bypass switches for flexible power distribution management.
• Operates over an extended industrial temperature range up to +150 °C.

Applications

• Advanced portable electronic devices requiring efficient multi-rail power sequencing
• Industrial control systems operating in high-temperature environments
• Automotive infotainment or telematics units

Procurement Notes

Verify the specific suffix (103SR) against official Qorvo documentation to confirm pinout and electrical characteristics. Confirm availability status as supply may be limited or restricted in certain regions. Ensure compatibility with WLCSP-30 assembly processes during procurement planning.

Selection Notes

Select this PMIC when a compact solution is required for systems needing three independent buck outputs and two LDOs. Consider the WLCSP-30 footprint constraints and thermal performance requirements. Validate that the 2.7 V to 5.5 V input range matches the system's power source capabilities.

Part Context

This component belongs to Qorvo's ACT8832x series of advanced PMICs. These devices are engineered for high integration in space-constrained applications. The series typically targets mobile and industrial markets where power efficiency and small form factors are critical design parameters.

Replacement Considerations

Check Qorvo datasheets for direct cross-references within the ACT8832x family. Verify if variants like ACT88321VU107SR offer identical functionality with different output configurations. Ensure any substitute maintains the WLCSP-30 package and thermal specifications.
