LM2743MTCX Description

Short technical summary and product information.

The LM2743MTCX from Texas Instruments is a versatile DC/DC switching controller operating in voltage mode. It is designed for synchronous buck converter applications, offering a wide input voltage range from 2.2V to 16V and an adjustable output voltage down to 0.6V.

 

Key electrical features include a maximum duty cycle of 80%, a switching frequency adjustable from 50 kHz to 1 MHz, and a typical quiescent current of 0.0015A. The controller supports synchronous rectification for improved efficiency. Control features include Enable, Power Good, Soft Start, and Tracking, along with output overvoltage and undervoltage detection and low-side adjustable current sensing.

 

This component is housed in a 14-TSSOP package, suitable for surface mounting. The operating temperature range is -40°C to 125°C (TJ). The feedback voltage accuracy is ±2% over temperature. The LM2743MTCX is designed for applications requiring efficient and stable step-down voltage conversion.
