ACT8865QI405-T

Overview

The ACT8865QI405-T is a specialized Power Management IC (PMIC) from Qorvo, designed for professional applications. It integrates three buck converters and four Low Dropout (LDO) regulators within a single QFN-32 package. The device operates with an input voltage range of 2.7 V to 5.5 V. Output currents are specified at 320 mA, 1.15 A, and 1.3 A depending on the regulator channel. The maximum output voltage reaches 3.3 V, while the minimum operating temperature is -40°C and the maximum is +85°C. Quiescent input current is 14 mA.

Feature Summary

• Integrates multiple power regulation stages including buck converters and LDOs in a compact form factor.

Applications

• Professional power management systems requiring integrated voltage regulation.

Procurement Notes

Verify the specific suffix '405' against official Qorvo documentation to confirm exact pinout and electrical characteristics, as suffixes often denote specific configuration or packaging variants. Ensure compatibility with the target PCB layout for the QFN-32 package. Confirm thermal requirements for the intended operating environment between -40°C and +85°C. Cross-reference the datasheet for any recent Product Change Notices that may affect performance or availability.

Selection Notes

Select this component when a multi-rail power solution is required for professional electronics. The integration of both switching regulators and linear regulators allows for efficient power conversion alongside low-noise supply needs. Consider the QFN-32 footprint constraints and the 2.7 V to 5.5 V input window. Evaluate if the combined output capabilities meet the system's total power budget without exceeding individual channel limits.

Part Context

This part belongs to the ACT8865 series of PMICs manufactured by Qorvo. The series is categorized under professional power management solutions. Other variants in the family may differ in output configurations or package types, such as the ACT8865EVK1-305 evaluation kit or the ACT8865QI305-T variant. These components share the same core architecture but may offer different regulatory combinations.

Replacement Considerations

Direct substitutes include other ACT8865 series parts like ACT8865QI305-T, provided the specific output configurations match the design requirements. Verify pin-to-pin compatibility and electrical specifications before substitution.
