LM5180QNGURQ1 – TEXAS INSTRUMENTS

The Texas Instruments LM5180QNGURQ1 is a 60V, 10A synchronous step-down converter housed in a thermally enhanced, 20-pin QFN package (7x7mm). This device utilizes a current mode control architecture for precise output voltage regulation and fast transient response, making it ideal for applications requiring high efficiency and low output voltage ripple. Its input voltage range spans 4.5V to 60V, supporting a wide variety of input sources. The LM5180QNGURQ1 features an adjustable output voltage, typically ranging from 0.8V to 58V, achievable through external resistor programming. Internal compensation simplifies design, minimizing external component count. Key features include programmable soft-start, overcurrent protection with hiccup mode, and thermal shutdown, enhancing system robustness. This makes it particularly suitable for applications such as industrial motor control, distributed power systems, and high-power LED drivers where high efficiency, wide input voltage tolerance, and compact size are crucial. Its 95% peak efficiency at 12V output minimizes power loss, contributing to improved system thermal management and extended battery life in portable applications. The Q1 suffix denotes a specific quality grade and testing level.
