ACT88430QJ120-T

Overview

The ACT88430QJ120-T is an integrated ActivePMU™ power management unit designed for processor applications. It features a wide input voltage range of 2.7 V to 5.5 V and a maximum output voltage of 3 V. The device integrates four DC-DC step-down converters, including one 4A regulator with bypass capability, and three LDOs. It operates at high switching frequencies up to 2.25 MHz, enabling compact designs with minimal external components.

Feature Summary

• Integrates four DC-DC buck regulators and three LDOs for comprehensive power distribution
• Features a 4A buck converter with bypass mode for efficient 3.3V system support
• Supports I2C configuration for dynamic adjustment of output voltages and sequencing
• Includes multi-level protection mechanisms such as over-voltage, under-voltage, and thermal monitoring

Applications

• Solid State Drives (SSD)
• Video processors
• FPGA systems
• NXP i.MX6UL/i.MX6ULL platforms

Procurement Notes

Verify the specific suffix J120 against the official Qorvo datasheet to confirm pinout and electrical characteristics. Confirm current manufacturing status as some listings indicate discontinuation. Ensure compatibility with required I2C addresses and package dimensions before integration into the design.

Selection Notes

Select this component when a single IC solution is needed for complex processor power rails. It is suitable for applications requiring precise voltage regulation and flexible sequencing via software. Consider the 40-QFN package constraints and thermal requirements for high-current buck channels in dense PCB layouts.

Part Context

This part belongs to Qorvo's Advanced PMIC family, optimized for embedded computing and storage solutions. It replaces discrete power architectures by consolidating multiple regulators into a single chip, reducing board space and simplifying supply chain management for video and FPGA-based systems.

Replacement Considerations

Check for direct substitutes within the ACT88430 series or compatible Qorvo PMICs. Verify pin-to-pin compatibility if replacing existing designs. Note that the ACT88329 shares similar functionality but may have different regulator counts or package options.
