LM2676SDX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2676SDX-ADJ is a SIMPLE SWITCHER® high-efficiency 3A step-down voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 8V to 40V and provides an adjustable output voltage from 1.2V to 37V. The device integrates a 3A power switch and features a fixed switching frequency of 260kHz. It utilizes a VSON-14 package for surface-mount applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 3A power switch for high current capability
• Fixed 260kHz switching frequency reduces external component size
• Adjustable output voltage range supports diverse design requirements

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient step-down conversion
• General-purpose DC/DC converter designs

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and tape/reel specifications against the official datasheet to ensure compatibility with automated assembly processes. Confirm RoHS compliance status as manufacturing revisions may alter environmental declarations. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for 3A load currents with an input voltage up to 40V. The adjustable output allows flexibility in setting precise voltage levels. Ensure thermal management strategies are adequate for the VSON-14 package given the power dissipation characteristics at higher load currents and input-output differentials.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2676 family of SIMPLE SWITCHER regulators, designed for high efficiency and ease of use. The SDX variant specifically denotes the VSON-14 surface-mount package, distinguishing it from TO-263 or TO-220 versions within the same electrical specification family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include other LM2676 series variants with compatible packages or pinouts, such as LM2676SX-ADJ/NOPB for D2PAK applications. Verify that substitute parts maintain the same 3A current rating and 260kHz switching frequency to preserve circuit performance.
