LM22673MR-ADJ Description

Short technical summary and product information.

The Texas Instruments LM22673MR-ADJ is a versatile step-down (buck) voltage regulator designed for a wide input voltage range of 4.5V to 42V. It can deliver up to 3A of output current.

 

Key electrical specifications include a nominal switching frequency of 500 kHz and a typical quiescent current of 3.4 µA. The device offers adjustable output voltage options as low as 1.285V, with a maximum output voltage of 37V. It utilizes voltage mode control and is internally compensated, making it stable with low ESR ceramic capacitors.

 

Features such as adjustable soft-start and adjustable current limit provide design flexibility. The operating temperature range is -40°C to 125°C. The LM22673MR-ADJ is available in HSOIC (DDA) and TO-263 (NDR) packages, both supporting surface mount installation.

 

This regulator is suitable for various power management applications requiring efficient voltage conversion within a broad input voltage range.
