Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM22672QMRX-ADJ/NOPB

LM22672QMRX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22672QMRX-ADJ/NOPB is an automotive-grade, adjustable step-down switching voltage regulator from the SIMPLE SWITCHER family. It operates with an input voltage range of 4.5 V to 42 V and delivers a maximum output current of 1 A. The device integrates a 1.1-MΩ resistor network for setting the output voltage and features a fixed internal switching frequency of 500 kHz. It utilizes an SO-PowerPAD-8 package for efficient thermal performance and includes comprehensive protection mechanisms such as cycle-by-cycle current limiting, thermal shutdown, and undervoltage lockout.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-side N-channel MOSFET enables compact design with minimal external components
Automotive qualification ensures reliability in harsh operating environments
Built-in thermal shutdown and cycle-by-cycle current limit protect against overload conditions

Voltage Regulators - DC DC Switching Regulators Applications

Automotive infotainment systems
Telematics control units
Body electronics power distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix QMRX indicates automotive grade and reel packaging. Confirm NOPB denotes lead-free/RoHS compliance. Ensure the ADJ variant matches the required adjustable output configuration rather than a fixed voltage option.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an automotive-rated buck converter is required for inputs up to 42 V. The 1 A output capacity suits moderate load applications. Verify that the 500 kHz switching frequency aligns with EMI constraints and inductor size requirements for the specific design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22672 series of SIMPLE SWITCHER regulators. It is the automotive-qualified version (indicated by the 'Q' prefix) of the commercial LM22672. The QMRX suffix specifies the SO-PowerPAD-8 package and tape-and-reel shipping format.
