ACT88430VM114-T

Overview

The ACT88430VM114-T is an advanced power management integrated circuit (PMIC) manufactured by Qorvo, designed specifically for microcontroller and solid-state drive applications. This device integrates four high-efficiency DC-DC buck converters and three low-dropout linear regulators (LDOs). Key electrical specifications include a wide input voltage range of 2.7V to 5.5V, supporting diverse power sources such as lithium batteries and USB supplies. The buck converters operate at a switching frequency of 2.25MHz, enabling the use of compact external components. Output voltages are adjustable from 0.6V to 4.0V via I2C interface, allowing precise configuration for various processor cores and peripheral circuits.

Feature Summary

• Integrates four synchronous buck converters and three LDOs within a single package to reduce component count and PCB area.
• Features intelligent software-defined configuration via I2C interface, allowing dynamic adjustment of output voltages, sequencing, and slew rates without hardware modifications.
• Includes comprehensive protection mechanisms such as input over-voltage/under-voltage monitoring, independent over-current protection per channel, and thermal management.
• Supports sequential startup functionality to ensure stable power-up sequences for complex processors and prevent system lockups.

Applications

• Microcontroller systems requiring multi-rail power distribution
• Solid State Drive (SSD) power architectures
• Smart cameras and IoT edge devices
• Industrial controllers with strict reliability requirements

Procurement Notes

Verify the specific suffix VM114-T against your bill of materials, as packaging and tape specifications may vary. Confirm end-of-life status or discontinuance notifications directly with Qorvo or authorized distributors, as availability for this specific part number may be limited. Ensure compatibility with your existing I2C address configurations and thermal design constraints before finalizing procurement orders.

Selection Notes

Select this PMIC when designing systems that require high integration density and flexible power sequencing for microcontrollers or SSDs. It is suitable for applications needing a wide input voltage range compatible with standard battery or USB rails. Consider its thermal performance and the need for external inductors/capacitors sized for 2.25MHz operation. Verify that the required output currents align with the specific buck and LDO channels provided in the datasheet.

Part Context

This component belongs to the Qorvo ACT88430 series of modular power PMICs. It represents a shift towards highly integrated solutions that replace discrete power management components. The series is engineered to meet the stringent efficiency and size constraints of modern embedded systems, offering a unified platform for managing complex power domains in portable and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Qorvo's official obsolescence notices or contact technical support for validated cross-references. Do not assume pin-to-pin compatibility with other ACT884x series parts without verifying detailed electrical and functional specifications.

FAQ
