ED8401P03QI

Power Management - Specialized Overview

The ED8401P03QI is a digital power controller manufactured by Altera, designed for multi-phase power management applications. It operates as a specialized PMIC featuring a 40-pin QFN EP package with dimensions of 5x5 mm. The device integrates a PMBus interface for communication and control, supporting switching frequencies up to 500kHz. It is specifically engineered to work in conjunction with the ET6160LI component, providing precise digital control for complex power conversion topologies.

Power Management - Specialized Feature Summary

• Integrates a PMBus interface for digital communication and system monitoring
• Provides digital control capabilities for multi-phase power conversion architectures
• Designed for compact integration within specialized power management IC solutions

Power Management - Specialized Applications

• Multi-phase voltage regulator modules requiring digital control
• Systems utilizing the ET6160LI companion component
• Compact power supply designs constrained by 40-QFN footprint requirements

Power Management - Specialized Procurement Notes

Verify the manufacturer designation carefully, as the part number appears associated with both Altera and Enpirion in public records. Confirm the specific datasheet version and pinout compatibility with your target PCB layout. Ensure that the 40-QFN EP package thermal pad connections meet your board's thermal dissipation specifications before finalizing procurement.

Power Management - Specialized Selection Notes

Select this component when a digital control interface is required for multi-phase power stages. The inclusion of PMBus support allows for advanced system-level monitoring and configuration. Consider the physical size constraints imposed by the 5x5 mm QFN package and ensure that the 500kHz operating frequency aligns with your electromagnetic interference and efficiency targets.

Power Management - Specialized Part Context

This component belongs to the class of specialized power management integrated circuits. While historically linked to Altera's broader portfolio, it functions as a dedicated digital controller rather than a programmable logic device. Its design focuses on integrating control logic directly into power conversion paths, distinguishing it from general-purpose microcontrollers or FPGAs.

Power Management - Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the specific integration with the ET6160LI and the unique digital control architecture, direct replacements may require significant circuit redesign. Consult official distributor channels for any officially recognized cross-reference parts.
