LM2674MX-3.3 Description

Short technical summary and product information.

The Texas Instruments LM2674MX-3.3 is a high-efficiency, 500mA step-down (buck) switching voltage regulator. It is designed to provide excellent line and load regulation with a fixed 3.3V output voltage. This regulator operates at a switching frequency of 260 kHz, which allows for the use of smaller filter components compared to lower frequency regulators.

 

Key features include an efficiency of up to 96%, a wide input voltage range of 8V to 40V, and a guaranteed 500mA output load current. The device includes internal frequency compensation and a fixed frequency oscillator. It also features current limiting and thermal shutdown for protection under fault conditions. The LM2674MX-3.3 is available in an 8-SOIC package, suitable for surface mount applications.

 

This regulator is ideal for simple, high-efficiency step-down power supply designs. It requires a minimal number of external components, simplifying the design process. Computer design software is available to further assist in the design procedure.
