ARG81401KLPATR

Overview

The ARG81401KLPATR is a DC-DC switching regulator IC manufactured by Allegro MicroSystems. It functions as a buck converter, designed to step down input voltage levels efficiently. The device is housed in a 20-TSSOP package with an exposed pad (EP), measuring 0.173 inches (4.40mm) in width. This surface-mount component integrates power management circuitry for stable voltage regulation in electronic systems.

Feature Summary

Integrated buck converter topology for efficient voltage stepping
Surface-mount design utilizing a 20-TSSOP package with exposed thermal pad
Built-in protection mechanisms inherent to the regulator architecture

Applications

General-purpose voltage regulation in industrial electronics
Power supply stages in consumer devices requiring stepped-down DC voltage
Embedded systems utilizing Allegro MicroSystems power management solutions

Procurement Notes

This component has been officially declared obsolete and is no longer in manufacturing production. Verification of availability should focus on distributor surplus stock or authorized replacement channels. Buyers must confirm the specific revision status and ensure that any substitute components meet the original electrical and mechanical specifications before integration into designs.

Selection Notes

Designers seeking this part must account for its end-of-life status when planning long-term production runs. Selection criteria should prioritize compatibility with the 20-TSSOP footprint and thermal requirements associated with the exposed pad. Engineers are advised to evaluate recommended manufacturer substitutes immediately to ensure supply chain continuity and maintain system performance standards without redesigning the PCB layout.

Part Context

The ARG81401KLPATR belongs to the ARG814 series of power management integrated circuits from Allegro MicroSystems. This series focuses on providing reliable switching regulator solutions for various applications. The specific model represents a standard buck converter configuration within this family, offering a compact solution for voltage regulation tasks in modern electronic assemblies.

Replacement Considerations

Allegro MicroSystems recommends the A4409KLPTR-T as a direct substitute for this obsolete part. Designers should verify pinout compatibility and electrical parameters against the new component datasheet to ensure seamless integration without modifying the existing board design.
