LM5000EVAL

The LM5000EVAL from Texas Instruments is an evaluation board and tool for the LM5000 family of offline switching power supply controllers. It is intended for use by power supply designers to quickly and easily evaluate many of the features of the LM5000 family of controllers. With the LM5000EVAL, engineers can evaluate the LM5000 for its ability to accurately control a wide variety of DC/DC and AC/DC converters, including buck, boost, flyback, forward, and bridge topologies.

The LM5000EVAL offers a wide range of features and capabilities as well as an extensive library of example designs. It is affordable and has a compact form factor, making it well suited for benchtop testing. The board is also very easy to use thanks to its graphical user interface and intuitive menus. The board includes features such as auto-detection and a trigger option for synchronizing external circuits and power supplies. Additionally, the board includes options for testing other components, such as secondary side regulators, rectifier diodes, and current sense resistors.

The LM5000EVAL comes pre-configured with the LM5000 controller for easy evaluation and testing of the controller. The user can also use the board to configure and program the LM5000’s on-chip registers for custom designs. The board includes an ISABUS interface with 48 pins for interfacing with the controller’s on-chip debugging interface. The ISABUS compatibility allows the board to be easily integrated with existing development systems, such as Texas Instruments’ Code Composer Studio platform, which provides a complete environment for debugging, compiling, and simulating embedded applications.

The LM5000EVAL also includes an oscilloscope to allow for observation of the input power supply voltage, load current, switch node, and output voltage. Additionally, each pin on the ISABUS interface has a corresponding break point that allows the user to observe the active values on the interface. This enables the user to observe the behavior of the controller and power supply under varying conditions. The board also includes a temperature probe to allow monitoring of the temperature of the controller and components.

The LM5000EVAL is a great tool for power supply evaluation, development, and testing. It provides the user with an easy to use, compact platform for evaluating the LM5000 controller. Additionally, the advanced features, such as the oscilloscope and temperature probe, provide the user with the insights needed to design a high performance power supply. Whether you are designing a buck, boost, flyback, forward, or bridge topology, the LM5000EVAL is an excellent evaluation board for evaluating and testing the LM5000 controller.
