Overview

Description

The LM5168FDDAR is a high-efficiency, step-down (buck) DC-DC converter from Texas Instruments. It is designed to provide power regulation for a wide range of applications, with an input voltage range from 6 V to 100 V, making it suitable for industrial, automotive, and telecom applications. The device can deliver up to 1.5 A of continuous output current, ensuring robust performance in demanding environments.
Key features include a constant-on-time (COT) control topology, which simplifies the design, reduces the need for external components, and allows for fast transient response. It also offers low IQ (quiescent current), improving efficiency during light-load conditions. The LM5168FDDAR is equipped with various protection features such as under-voltage lockout (UVLO), thermal shutdown, and current limiting to ensure reliable operation.
Its small footprint, with a 10-pin VSON package, and high efficiency make it ideal for space-constrained applications. Additionally, the converter supports external frequency synchronization, enabling designers to reduce interference in sensitive applications. Overall, the LM5168FDDAR is a versatile and reliable choice for efficient power conversion in high-voltage applications.
