LM22673QMRE-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22673QMRE-ADJ/NOPB is a SIMPLE SWITCHER step-down voltage regulator manufactured by Texas Instruments. It features an integrated power switch capable of delivering up to 3 A output current. The device operates with an input voltage range from 4.5 V to 40 V and provides an adjustable output voltage. It utilizes a fixed switching frequency of 500 kHz. The component is housed in an SO-PowerPAD-8 surface-mount package. It supports operation across an extended temperature range from -40°C to +125°C and holds AEC-Q100 qualification for automotive applications.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMRE' corresponds to the SO-PowerPAD-8 package variant when sourcing. Confirm that the 'ADJ' designation indicates the adjustable output version rather than a fixed voltage option. Ensure compatibility with AEC-Q100 requirements if deploying in automotive environments. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a 3 A buck converter with adjustable output within a 4.5 V to 40 V input window. Consider the 500 kHz switching frequency for balancing component size and efficiency. Evaluate thermal performance due to the integrated power switch. Compare against the LM2673 series for legacy pin-compatible alternatives if through-hole mounting is required.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22673 family of SIMPLE SWITCHER regulators, designed for high-efficiency DC-DC conversion.
