The Texas Instruments LM2647MTCX is a highly efficient, dual-output, synchronous buck controller IC. Designed for step-down DC-DC conversion, this device operates from a wide input voltage range of 5.5V to 28V. It features a flexible switching frequency adjustable from 200kHz to 500kHz, with a maximum duty cycle of 75%. The LM2647MTCX includes essential control features such as current limit, enable, frequency control, power good indication, and soft start for robust power management. Its positive output configuration and two output phases, driven by transistor drivers, enable versatile power supply designs. This component is commonly utilized in applications such as power supplies for consumer electronics, telecommunications equipment, and industrial control systems. The LM2647MTCX is supplied in a 28-TSSOP package, suitable for surface mount assembly, and is delivered on a tape and reel. It supports synchronous rectification for improved efficiency.
