LM5071MTX-80/NOPB

Overview

The LM5071MTX-80/NOPB is a synchronous buck controller from Texas Instruments designed for high-efficiency power conversion. It operates with an input voltage range of 4.5V to 60V and supports output voltages down to 0.9V. The device integrates an N-channel driver capable of sourcing and sinking up to 2A of peak gate current, enabling the use of external low RDS(on) MOSFETs. It features adjustable switching frequencies from 300kHz to 2.2MHz and includes comprehensive protection mechanisms such as cycle-by-cycle current limiting, overvoltage protection, and thermal shutdown. The component is housed in a thermally enhanced WSON-10 package.
