LM2672N-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672N-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator designed for through-hole mounting in an 8-pin MDIP package. It provides a fixed 5V output with a maximum load current of 1A. The device operates from an input voltage range of 6.5V to 40V and features a switching frequency of 260kHz. It supports a junction temperature range from -40°C to +125°C, includes internal thermal shutdown and current limiting, and complies with RoHS standards.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-side switch eliminates the need for external Schottky diodes
• Fixed 5V output option simplifies design by reducing external component count
• Internal thermal shutdown and current limit protect against overload conditions

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient step-down conversion
• Industrial control modules operating within wide input voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance. Confirm the N suffix corresponds to the MDIP through-hole package rather than surface-mount variants. Ensure the specific revision matches your schematic requirements as pinouts remain consistent across the series but packaging differs significantly between SOIC and DIP options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V output is required without external feedback resistors. Choose the through-hole MDIP package for prototyping or applications requiring mechanical robustness over board space constraints. Verify that the 1A output current meets the load demand, considering derating at higher ambient temperatures near the upper operational limit.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2672 series of SIMPLE SWITCHER regulators, which are known for low external component counts. Unlike adjustable versions, the fixed output variant integrates the feedback network internally. It serves as a direct replacement for older discrete buck converter designs, offering improved efficiency and reduced board area compared to linear regulators in high-differential applications.
