LM22675MRE-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22675MRE-ADJ/NOPB is a step-down switching voltage regulator from Texas Instruments, operating within the SIMPLE SWITCHER family. It integrates a high-side N-channel MOSFET to deliver up to 1A of output current. The device supports an input voltage range of 4.5V to 42V and features an adjustable output voltage starting from 1.285V. It operates at a fixed switching frequency of 500kHz and utilizes an SO-PowerPAD-8 package for surface mount installation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MRE' 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 the required thermal management solutions for the exposed pad configuration during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a single-output buck converter with moderate current capacity. The adjustable output allows flexibility for various target voltages above 1.285V. Consider the 500kHz switching frequency for balancing efficiency against passive component size requirements in space-constrained layouts.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22675 series, which offers higher current capability compared to the LM22674 (500mA) and lower current than the LM22673 (3A). It shares the same 500kHz switching architecture and package options as other members of the family, providing a scalable solution for different power levels within the same design ecosystem.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22675MRX-ADJ/NOPB serves as a reel-based alternative with identical electrical characteristics. LM22675QMR-5.0/NOPB is a qualified automotive-grade variant but provides a fixed 5V output instead of adjustable.
