LM2672MX-3.3 Description

Short technical summary and product information.

The LM2672MX-3.3 from Texas Instruments is an integrated circuit designed for step-down (buck) DC/DC conversion. This regulator features a low component count, simplifying circuit design and reducing board space. It can deliver up to 1A of output current and accepts a wide input voltage range from 6.5V to 40V.

 

The device operates at a fixed switching frequency of 260kHz, contributing to its high efficiency of up to 96%. The LM2672MX-3.3 is specifically configured for a fixed 3.3V output voltage. Key features include enable and overcurrent protection functionalities, operating in voltage mode control.

 

This regulator is housed in an 8-SOIC surface mount package, measuring 4.9 mm x 6 mm. Its operating temperature range is -40°C to 125°C (TJ). The design requires only five external components, making it suitable for applications where space and design complexity are critical factors.
