The LM2674MX-5.0/NOPB is a 500mA, Step-Down Voltage Regulator Power Converter from Texas Instruments' wide range of Switching Voltage Regulators. It supplies an output voltage ranging from 4.75V to 5.5V with a wide input voltage range of 4.5V to 18V. This compact, low-power solution is specifically designed for consumer, automotive, and industrial applications such as buck, boost, and SEPIC converters. Its features include soft-start and short-circuit protection, internal synchronous rectification for increased efficiency, and adjustable frequency. This switching regulator includes thermal shutdown and over-temperature protection to guard against temperature abnormalities. Additionally, its low-noise operation (50µVrms switching noise at 500kHz) makes it an ideal choice for noise-sensitive GHz RF applications. The LM2674MX-5.0/NOPB is offered in a 3-Pin PowerPAD package for thermal, electrical, and mechanical performance.
