LM2672MX-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672MX-5.0/NOPB is a SIMPLE SWITCHER® high-efficiency 1A step-down voltage regulator from Texas Instruments, housed in an 8-SOIC package. It operates with an input voltage range of 6.5V to 40V and provides a fixed positive output of 5V at up to 1A. The device integrates a 260kHz switching frequency, enabling the use of small external components. It features a low quiescent current of 2.5mA and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a power switch for simplified design
• Utilizes internal compensation for stability
• Supports low component count architecture

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation modules
• Battery-powered systems requiring step-down conversion
• General-purpose DC/DC power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB indicates lead-free and RoHS compliance as per manufacturer specifications. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the fixed 5V output variant aligns with your circuit design needs rather than adjustable versions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V output is required from an input voltage between 6.5V and 40V. The 1A current rating suits moderate load applications. Consider the 260kHz frequency for balancing efficiency and passive component size compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2672 series of SIMPLE SWITCHER regulators. It is distinct from the LM2574 series which typically operates at lower frequencies and may have different current ratings or pin configurations. The MX suffix denotes the specific tape-and-reel packaging format.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2672 variants with compatible output voltages, such as LM2672M-ADJ for adjustable outputs. Cross-reference with LM2672MX-3.3/NOPB for 3.3V fixed output requirements while maintaining the same package and performance characteristics.
