Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM22674MRX-5.0/NOPB

LM22674MRX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22674MRX-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down DC/DC switching regulator in an SO-PowerPAD-8 package. It provides a fixed 5 V output with a maximum current of 500 mA. The device accepts an input voltage range of 4.5 V to 42 V and operates at a fixed switching frequency of 500 kHz. Typical quiescent current is 3.4 mA. It supports operation from -40°C to +125°C and includes precision enable functionality.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated power switch for compact buck converter design
Precision enable pin for controlled startup sequencing
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
Industrial control modules operating within wide input ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against the manufacturer datasheet to confirm fixed output voltage and package type. Ensure the ordering part number matches the required tolerance and temperature rating. Confirm RoHS compliance status through official documentation before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a high-voltage input source up to 42 V. The 500 mA current capability suits low-power applications. Consider the SO-PowerPAD-8 package for thermal performance and space constraints compared to standard SOIC packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22674 family of SIMPLE SWITCHER regulators. It shares topology and features with adjustable variants like the LM22674MRX-ADJ/NOPB but offers a fixed 5 V output. It is distinct from higher-current models such as the LM22676 series which support up to 3 A outputs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22674MRX-5.0/NOPB is functionally equivalent to LM22674QMRX-5.0/NOPB, differing primarily in automotive qualification (AEC-Q100). Direct substitutes include other fixed-output versions within the same LM22674 series.
