The LM5119EVAL/NOPB is an excellent example of evaluation boards for DC/DC & AC/DC (Off-Line) SMPS. The board is designed for developers of power supply systems and has many features to help reduce design risk and speed the development process. This evaluation board effectively eliminates the need for in-circuit testing of the LM5119, allowing for a quick and easy evaluation.

The LM5119EVAL/NOPB is based on ON Semiconductor’s LM5119 controller IC. This application can be used in various power supply designs, such as buck converters, boost converters, flyback converters, and other forms of DC/DC & AC/DC converters. Furthermore, the board includes dedicated test points and features, such as voltage sensing, AmpSense current sensing, overvoltage protection, and enable/shutdown logic. All of these features offer convenience and flexibility to power supply developers.

The LM5119EVAL/NOPB evaluation board is designed to simplify the process of evaluating the performance of the LM5119 controller IC. The board is powered by a 15V DC input, and includes key components, such as the controller, MOSFETs, inductors, capacitors, and resistors. Moreover, theevaluation board provides a comprehensive set of features, such as selectable current limiting, frequency compensation, thermal shutdowns, soft-start, and under-voltage Lock-out.

The LM5119EVAL/NOPB’s working principle begins with the application of power to the system. This initial power is handled by the on-board MOSFETs that convert the input voltage into controlled output voltage as depicted in a Buck Converter. The current at the output of the converter is controlled by the controller’s internal current-limit circuitry, making it possible to maintain robust operation of the converter.

The LM5119EVAL/NOPB evaluation board is also versatile when it comes to adapting to different applications. The board can be used to evaluate any kind of SMPS design, because the user can set the output voltage of the circuit with the on-board potentiometer, and adjust frequency, compensation, and current limit through the various on-board jumpers.

The on-board AmpSense current sensing feature enhances design flexibility as well. This feature allows for accurate current monitoring of all components, allowing for robust operation and less design complexity. Furthermore, the on-board Enable/Shutdown logic makes it possible to control the power output from the converter as desired.

The LM5119EVAL/NOPB approval board is an excellent tool for developers of DC/DC & AC/DC (Off-Line) SMPS. This evaluation board makes it convenient and easy to evaluate the performance of the LM5119 controller IC, as well as testing different design applications for your power supplies. The board\'s versatile combination of features and components offers developers convenience and flexibility to develop robust and efficient power source systems.
