The LM25116EVAL is a low voltage, synchronous DC-DC buck controller with integrated gate drivers, and it is classified as an evaluation board for DC/DC & AC/DC SMPS systems. This application field is ideal for applications that require high efficiency and low output voltage ripple, such as computer monitors, TVs, networking equipment and portable device power supplies. The low voltage operating range means that it can be used outside the range of typical DC/DC converters.

The LM25116EVAL is a fully integrated and configurable design that can be used to evaluate the features and performance of Texas Instrument\'s LM25116 buck controller. It features integrated synchronous rectification circuitry for improved system efficiency and transient response, and it’s designed to optimize the performance of applications with small output currents. The LM25116EVAL also includes an integrated temperature sense circuit which enables the device to protect itself from operating outside its specified temperature range.

The LM25116EVAL board uses a two-stage configuration including one input capacitor and two output inductors. The input capacitor helps to reduce high frequency noise and minimize input current ripple. The output inductors are used to provide regulated output voltage at varying input voltage ranges. The board also includes a short circuit protection to protect the device from any failure.

The LM25116EVAL includes all the necessary components for operating at up to 96% efficiency. It features an integrated Digital Power System Manager (DPSM) which constantly monitors system performance and allows the device to be adjusted to guarantee stable operation even at low load currents. The device includes a PMBus™ capable I²C interface giving users the ability to monitor and control the device remotely.

The DPSM on the LM25116EVAL board allows the user to implement a number of features, including real-time output voltage monitoring, programmable power limit thresholds, adjustable switching frequency, and selectable continuous or triggered output voltage modes. The board also includes an integrated gate driver for improved system efficiency and increased device operational lifetime. Users can configure the voltage mode, current limit, soft start delay, and frequency settings by using the I²C interface.

The LM25116EVAL is a great choice for both AC and DC power applications, and it is designed for system designers and engineers looking to evaluate how the LM25116 buck controller can help meet their specific power requirements. This low voltage buck controller is designed to meet a variety of power system requirements, while at the same time ensuring high efficiency and low output voltage ripple.
