LM2674MX-12 Description

Short technical summary and product information.

The Texas Instruments LM2674MX-12 is a high-efficiency, 500 mA step-down (buck) switching regulator. It provides a fixed 12V output voltage with excellent line and load regulation. This monolithic integrated circuit is built with a LMDMOS process and requires minimal external components for operation.

 

Key electrical specifications include a wide input voltage range of 8V to 40V, a guaranteed 500mA output load current, and a switching frequency of 260kHz. This higher frequency allows for smaller filter components compared to lower-frequency regulators. The device boasts efficiency up to 96% and includes features like current limiting and thermal shutdown for protection.

 

Designed for ease of use, the LM2674MX-12 is suitable for various power supply applications. It is available in a surface-mount 8-SOIC package, making it convenient for PCB integration. The regulator also features external shutdown capability with low standby current.

 

This component is ideal for applications requiring efficient voltage conversion. Its robust design and integrated features simplify the development of switch-mode power supplies.
