ACT88430VM114SR

Overview

The ACT88430VM114SR is a specialized Power Management IC (PMIC) manufactured by Qorvo, designed for advanced processor and storage applications. It integrates four high-efficiency DC-DC buck converters and three Low Dropout (LDO) regulators within a single compact package. The device supports an input voltage range of 2.7 V to 5.5 V, accommodating various power sources including lithium batteries and USB supplies. Key electrical specifications include a peak current capability of 4 A on the primary buck channel, with standard channels supporting 2.5 A. The LDO outputs provide currents of 800 mA and two channels at 200 mA. Operating frequencies reach up to 2.25 MHz, enabling the use of small external passive components. The component is housed in a WLCSP-90 package suitable for surface mount technology.

Feature Summary

• Integrates four synchronous buck converters and three LDOs for comprehensive multi-rail power delivery
• Features software-configurable parameters via I2C interface for flexible system adaptation without hardware changes
• Includes integrated protection mechanisms such as over-voltage, under-voltage, and thermal shutdown
• Supports serialized startup sequencing to ensure stable power-up for complex processor systems

Applications

• Solid State Drives (SSD)
• Video processors and AI accelerators
• Field Programmable Gate Arrays (FPGA)
• Microcontrollers and embedded controllers

Procurement Notes

Verify the specific suffix VM114SR against official Qorvo documentation to confirm pinout compatibility and temperature grade. Ensure the design-in process accounts for the WLCSP-90 packaging requirements during PCB layout. Confirm that the selected supplier provides genuine parts with traceability to the manufacturer. Check for any recent lifecycle notifications regarding production status or recommended replacements.

Selection Notes

Select this PMIC when designing systems requiring high current density and multiple regulated rails from a single wide-input voltage source. It is suitable for space-constrained applications where reducing external component count is critical. Consider its I2C configurability if the design requires post-manufacturing adjustments to voltage levels or timing sequences. Evaluate the thermal performance of the WLCSP package relative to the expected load conditions.
