LM22671MRE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22671MRE-5.0/NOPB is a fixed-output buck converter from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It provides a regulated 5 V output with a maximum continuous current of 500 mA. The device accepts an input voltage range of 4.5 V to 42 V and operates at a switching frequency of 500 kHz. It features a quiescent current of 3.4 mA and supports an operating temperature range from -40 °C to +125 °C. The component is housed in an 8-SO-PowerPAD package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-side switch for efficient step-down conversion
• Built-in thermal shutdown and overcurrent protection mechanisms
• Fixed 5 V output configuration eliminates external feedback resistor requirements

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Power supply stages in industrial control equipment
• Voltage regulation for automotive electronics subsystems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to confirm the fixed 5.0 V output variant. Ensure the SO-PowerPAD-8 package matches the target PCB footprint. Confirm RoHS compliance status via the manufacturer datasheet before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required within a 4.5 V to 42 V input range. It is suitable for applications needing up to 500 mA load current without requiring adjustable output precision. Consider the 8-SO-PowerPAD package for thermal management needs in space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the LM2267x series of SIMPLE SWITCHER controllers. It shares architectural similarities with the LM22673 and LM22676 but differs in output current capacity. The LM22671 specifically targets lower power applications compared to the 3 A variants in the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22671MRX-ADJ/NOPB offers adjustable output instead of fixed 5 V. LM22673QMRE-5.0/NOPB provides higher 3 A current capability in a similar topology. Cross-reference pinouts and thermal characteristics before substituting.
