ACT88321VU101-T

Overview

The Qorvo ACT88321VU101-T is a specialized processor PMIC featuring three buck converters, two LDOs, and a load bypass switch. It operates within an input voltage range of 2.7 V to 5.5 V. The device supports output voltages from 600 mV to 3.775 V with a maximum output current of 4 A. It functions between -40°C and +125°C with a quiescent current of 260 uA. Packaged in a WLCSP-30 format, it targets high-density power management needs.

Feature Summary

• Integrates multiple voltage regulation stages including buck converters and LDOs for comprehensive power distribution.
• Offers configurable system-level sequencing and wake-up triggers via GPIOs for flexible design integration.
• Supports I2C interface for reconfiguration without hardware changes, reducing external component count.

Applications

• Solid-State Drives (SSD)
• Video processors
• FPGA applications

Procurement Notes

Verify the specific suffix 'VU101' against the official datasheet to confirm pinout and configuration settings. Ensure the WLCSP-30 package compatibility with your PCB layout constraints. Confirm that the operating temperature range meets your environmental requirements. Check for any recent Product Change Notifications (PCN) affecting the manufacturing process or materials.

Selection Notes

Select this PMIC when designing compact systems requiring integrated power management for processors or storage controllers. The WLCSP-30 package is suitable for space-constrained layouts. Consider the 4 A output capability for high-current rails. Verify that the 2.7 V to 5.5 V input range aligns with your system's power source availability.
