LM22672MRE-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22672MRE-ADJ/NOPB is a Texas Instruments SIMPLE SWITCHER® step-down voltage regulator featuring an integrated power switch. It operates within an input voltage range of 4.5 V to 42 V and delivers up to 1 A output current. The device utilizes a fixed 500 kHz switching frequency and provides adjustable output voltage. It includes thermal shutdown, current limit protection, and a shutdown pin for low quiescent current operation of 3.4 mA. The component is housed in an SO-PowerPAD-8 package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MRE' indicates reel packaging configuration distinct from tube variants. Confirm RoHS compliance status matches project requirements. Ensure the supplier documentation explicitly references the LM22672MRE-ADJ/NOPB part number to avoid confusion with non-NOPB or different package versions. Cross-reference the datasheet revision date against manufacturing lot codes for quality assurance.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck converter with 1 A capability is required. The 500 kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the input voltage does not exceed 42 V under all operating conditions. Consider the thermal performance of the PowerPAD package for heat dissipation needs in enclosed environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22672 series of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM22673 (3 A) and LM22674 (500 mA) variants but offers a specific 1 A output rating. The 'NOPB' designation confirms lead-free and halogen-free construction compliant with environmental standards.
