Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2671MX-5.0/NOPB

LM2671MX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2671MX-5.0/NOPB is a high-efficiency 500mA step-down voltage regulator from the Texas Instruments SIMPLE SWITCHER family. It operates with a fixed switching frequency of 260kHz and delivers a regulated 5V output. The device supports an input voltage range up to 40V, features a compact SOIC-8 package, and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic buck converter topology for simplified design
Fixed internal switching frequency reduces external component count
Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment requiring efficient step-down conversion
General-purpose 5V power supply generation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free compliance and RoHS adherence. Confirm the MX suffix corresponds to the SOIC-8 surface-mount package. Ensure the -5.0 designation matches the required 5V fixed output voltage for your specific circuit design requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output at 500mA is required from higher input voltages up to 40V. The 260kHz frequency allows for smaller inductors compared to lower-frequency regulators. Consider the SOIC-8 package constraints and thermal performance for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2671 SIMPLE SWITCHER series, designed for high-efficiency DC-DC conversion. It serves as a robust solution for replacing linear regulators in applications where heat dissipation and efficiency are critical concerns.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible alternatives include the LM2671M-5.0/NOPB (TO-263 package) or LM2671S-5.0/NOPB (TO-263 package). Verify thermal management capabilities differ significantly between SOIC-8 and larger packages.
