Texas Instruments LM2742MTCX is a high-performance, synchronous buck DC-DC controller IC. This device is designed for positive output step-down applications, featuring a robust set of control functions including current limit, enable, frequency control, power good signal, and soft-start. The LM2742MTCX operates with a wide switching frequency range from 50kHz to 2MHz, enabling efficient power conversion across various load conditions. Its 90% maximum duty cycle and single-phase, single-output configuration make it suitable for demanding power management tasks. The component is housed in a compact 14-TSSOP (0.173", 4.40mm Width) package, designed for surface mounting. Operating across an industrial temperature range of -40°C to 125°C (TJ), this Texas Instruments controller finds application in areas such as industrial power supplies and consumer electronics requiring efficient voltage regulation. The device is supplied on tape and reel (TR) for automated assembly.
