NCP3011GEVB is an evaluation board from ON Semiconductor for demonstrating the capabilities of the NCP3011 monolithic controller IC used in isolated AC/DC and DC/DC (off-line) switch mode power supply (SMPS) applications. NCP3011GEVB is designed to showcase the performance of the NCP3011 in both continuous and discontinuous conduction mode (CCM and DCM) applications. It includes a number of features that make it is ideal for designing and evaluating power supply systems, including various signal ports for easy monitoring, an embedded serial-controlled GUI, and external synchronous FET drive capability.

The NCP3011GEVB evaluation board is designed with a focus on isolated AC/DC and DC/DC switched mode power supply (SMPS) applications. It can be used to evaluate the NCP3011 monolithic controller IC in both continuous and discontinuous conduction mode (CCM and DCM) applications. The board has been designed and tested to support a power supply output rating of 12V to 38V and up to 10A. The board includes all the necessary signal inputs and outputs to help monitor and control the power supply, as well as a user-friendly serial-controlled graphical user interface for easy operation and evaluation.

The NCP3011GEVB evaluation board includes a number of features to facilitate easy and fast power supply design and testing. The board includes a Peltier device for generating temperature changes during testing and a STpMOS™ (Self-Timed Power MOSFET) driver to enable external synchronous FET drive capability. It also includes an external shunt resistor, allowing users to easily measure current during evaluation. The board also features several signal ports for easy monitoring, including a signal looping port, EMI ports, a mechanical on/off switch, and HD signal sense ports.

In terms of working principle, the NCP3011GEVB board is powered by a fixed voltage source, with the control voltage being generated by the NCP3011 monolithic control IC. The NCP3011 is configured to operate in either CCM or DCM. In CCM, the controller regulates the output voltage by modulating the duty cycle of the forcing switches. In DCM, it senses the voltage on the output capacitor and modulates the duty cycle based on that signal, allowing it to operate with fewer components and improved efficiency.

Overall, the NCP3011GEVB evaluation board is an ideal solution for evaluating the NCP3011 monolithic controller IC in both CCM and DCM applications. Its features and design make it easy to use and effective in providing the necessary information for developing AC/DC and DC/DC (off-line) SMPS designs. With the NCP3011GEVB board, users can quickly and accurately design, build, and test powerful and efficient power supply applications.
