LM2674M-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2674M-ADJ/NOPB is a Texas Instruments Simple Switcher step-down voltage regulator featuring an adjustable output. It operates with an input voltage range of 8 V to 40 V and delivers up to 500 mA of output current. The device integrates a 1.23 V reference and utilizes a fixed 260 kHz switching frequency. Packaged in an 8-pin SOIC PowerPAD, it supports operation from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a power switch for high-efficiency buck conversion
Includes internal frequency compensation for stable loop performance
Features thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation modules
Battery-powered systems requiring efficient step-down
General-purpose DC/DC conversion circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free status and RoHS compliance. Confirm the M package corresponds to the SOIC PowerPAD variant. Ensure the ADJ designation matches the requirement for an externally adjustable output voltage rather than a fixed value.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 40 V is required with moderate load currents around 500 mA. The adjustable output allows flexibility for various system rails. Consider the SOIC PowerPAD package for thermal management in space-constrained designs without external heatsinks.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 family of Simple Switcher regulators. It shares architectural similarities with other members like the LM2674N but differs in package type and mounting style. The family is designed for straightforward implementation of non-isolated DC-DC converters.
