Texas Instruments LM2743MTC is a high-performance, non-synchronous buck controller IC designed for efficient step-down DC-DC conversion. This device features a flexible switching frequency range from 50kHz to 1MHz, supporting a maximum duty cycle of 80%. The LM2743MTC offers robust control features including current limit, enable, frequency control, power good indication, soft start, and tracking capabilities. It is packaged in a 14-TSSOP (0.173", 4.40mm Width) for surface mounting. With a supply voltage range of 3V to 6V, this controller is well-suited for applications in the industrial and consumer electronics sectors requiring precise voltage regulation. The output configuration is positive, and it drives a single output phase. The operating temperature range is -40°C to 125°C (TJ).
