Texas Instruments Buck Converter, Surface Mount, 28V Output Voltage, 5A Output Current, SOIC Package, Model LMR14050SDDA

Texas Instruments LMR14050SDDA Buck Converter is a highly efficient surface mount switching regulator designed for power management applications requiring 28V output voltage and 5A continuous output current. The device utilizes SIMPLE SWITCHER® technology to provide robust, compact, and reliable voltage step-down conversion suitable for industrial, laboratory, and commercial electronics.

It comes housed in a compact SOIC package with 8 pins, measuring 5 mm in length, 4 mm in width, and 1.3 mm in depth, optimized for PCB space savings. Operating over a wide temperature range from -40°C to 125°C, it is capable of functioning reliably in industrial-grade and demanding environmental conditions.

The buck converter supports input voltages ranging from 4V to a maximum of 40V, making it compatible with a diverse range of power supply inputs. Its efficiency rating of 92% ensures minimal power loss while maintaining stable regulated output voltage with line regulation of 0.04 %/V. Integrated features include internal soft-start and thermal shutdown to prevent inrush currents and protect against overheating respectively.

Part of the LMR Nano SIMPLE SWITCHER® series, this device operates with a switching frequency of around 1MHz, balancing high performance with design flexibility and ease of use. It is ideal for power supply designers seeking a balance between high efficiency, compact size, and robust thermal performance.
