The LM2743MTC from Texas Instruments is a voltage mode synchronous buck controller designed for efficient power management. It features an input voltage range of 2.2-V to 16-V, with the control stage operating from 3V to 6V and the power stage from 1V to 16V. The output voltage is adjustable down to 0.6V, and it can handle a maximum output current of 20A.
This controller operates with a switching frequency adjustable from 50 kHz to 1 MHz, offering flexibility in design. Key control features include current limit, enable, frequency control, power good signal, soft start, and tracking capabilities. The device is housed in a 14-TSSOP package, suitable for surface mounting.
Additional features include ±2% feedback voltage accuracy over temperature, output overvoltage and undervoltage detection, and low-side adjustable current sensing. The synchronous rectification ensures high efficiency in buck conversion applications.
