LM26480SQX-BF/NOPB

Overview

The LM26480SQX-BF/NOPB is a Power Management Integrated Circuit (PMIC) from Texas Instruments, featuring two high-current synchronous step-down DC/DC converters and two low-dropout linear regulators. Designed for advanced application processors and FPGAs, it integrates precision internal references and protection features including thermal overload, current overload, and undervoltage lockout detection.

Feature Summary

• Integrates dual high-current buck regulators and dual LDOs in a single package
• Compatible with advanced application processors and FPGAs
• Includes precision internal reference for accurate voltage regulation
• Provides comprehensive protection against thermal, current, and undervoltage conditions

Applications

• Powering internal processor functions in advanced application processors
• Supplying I/O power for FPGA systems
• Multi-rail power management for digital logic applications

Procurement Notes

Verify the specific suffix BF against official Texas Instruments documentation to confirm pinout and electrical characteristics, as suffixes often denote package variations or specific revisions. Ensure compatibility with your board design by cross-referencing the WQFN-24 footprint and thermal pad requirements. Confirm that the AEC-Q100 qualification aligns with your automotive or industrial reliability standards before finalizing procurement.

Selection Notes

Select this component when designing systems requiring multiple regulated rails from a single input source. It is suitable for applications needing both high-efficiency switching for main loads and low-noise linear regulation for sensitive analog or digital cores. Consider the 24-pin WQFN package for space-constrained designs requiring integrated thermal dissipation capabilities.

Part Context

This device belongs to the LM26480 family of PMICs designed for complex digital systems. It consolidates multiple power stages into one compact solution, reducing component count and board area compared to discrete regulator implementations. The integration supports efficient power distribution networks for modern high-performance computing and communication devices.

Replacement Considerations

Check for LM26480 variants with different suffixes such as SQ-AA/NOPB or QSQX-8D/NOPB. Verify if alternative part numbers like LM26420Q1XSQX/NOPB meet the current and voltage requirements, noting differences in output configuration and package type.
