LM22672QMRE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22672QMRE-5.0/NOPB is a fixed-output buck converter from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It delivers a fixed 5V output with a maximum current of 1A. The device operates within an input voltage range of 4.5V to 42V and features an adjustable switching frequency up to 1.5MHz. It is housed in an 8-SO PowerPAD package and supports surface-mount installation. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Automotive-grade qualification ensures reliability in harsh environments

Voltage Regulators - DC DC Switching Regulators Applications

• Automotive infotainment systems
• Telematics control units
• Body electronics modules
• Industrial point-of-load regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '5.0' confirms the fixed 5V output variant, distinct from adjustable versions. Confirm AEC-Q100 qualification status if automotive deployment is required. Ensure the 8-SO PowerPAD footprint matches the PCB layout constraints. Check RoHS compliance documentation for environmental regulations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V rail is needed with up to 1A load capability. Consider the wide input voltage range suitable for 12V or 24V automotive buses. Evaluate thermal requirements due to the SOIC PowerPAD package. Compare against higher-current models like the LM22673 if load demands exceed 1A.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2267x series of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM22673 (3A) and LM22674 (500mA), differing primarily in output current capacity. The series offers a unified interface for designers scaling power requirements while maintaining consistent pinouts and control logic.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22672M-5.0/NOPB serves as a non-automotive grade alternative with identical electrical specifications but without AEC-Q100 certification. For higher current needs, the LM22673QMRE-5.0/NOPB provides 3A output in the same package.
