LM2671M-12 Description

Short technical summary and product information.

The LM2671M-12 from Texas Instruments is a high-efficiency, 500mA step-down (buck) switching voltage regulator. Built with LMDMOS process, it provides excellent line and load regulation.

 

This regulator operates at a fixed 260kHz switching frequency, enabling the use of smaller filter components compared to lower frequency regulators. It boasts efficiencies up to 96% and requires minimal external components for operation. The device features a wide input voltage range of 8V to 40V and a guaranteed 500mA output load current.

 

Key features include internal frequency compensation, soft-start, external shutdown capability, and frequency synchronization. For protection, it incorporates current limiting and thermal shutdown.

 

The LM2671M-12 is available in an 8-SOIC package and is designed for surface mounting. Its high efficiency means copper traces on the PCB often suffice for heat sinking.
