Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM22672MRX-ADJ/NOPB

LM22672MRX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22672MRX-ADJ/NOPB is a SIMPLE SWITCHER® step-down voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 42 V and provides a maximum output current of 1 A. The device features an adjustable output voltage, a fixed switching frequency of 500 kHz, and a typical quiescent current of 3.4 mA. It utilizes an 8-SO PowerPAD package for surface mount installation and supports an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-side and low-side MOSFETs enable efficient buck conversion within a compact footprint.
Adjustable switching frequency allows optimization for specific inductor size and efficiency requirements.
Built-in thermal shutdown and cycle-by-cycle current limit protect the device under fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Industrial control power supplies
Telecommunications equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance. Confirm the MRX suffix corresponds to the tape-and-reel packaging format rather than tube packaging. Ensure the ADJ designation matches the requirement for an adjustable output voltage configuration instead of a fixed voltage variant.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 42 V is required with a 1 A load capacity. The 500 kHz switching frequency offers a balance between component size and efficiency. Consider the SO-PowerPAD package for thermal performance in space-constrained designs requiring robust heat dissipation capabilities.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22672 SIMPLE SWITCHER family, which integrates power switches into a single monolithic IC. The series is designed to simplify power supply design by reducing external component count. The LM22672 variant specifically targets applications needing moderate current levels with wide input voltage flexibility.
