The NCP3102BUCK1GEVB uses an inductor and several ceramic capacitors to provide design flexibility for low-EMI and other applications. Working principle of the NCP3102BUCK1GEVB is simple. The board uses ON Semiconductor’s Synchronous Buck Controller IC, the NCP3102B. This IC is configured to reduce an input voltage to a lower output voltage, allowing for easy evaluation of the controller IC features and performance. The NCP3102B uses a hysteretic control loop to synchronize the controller to the input voltage, as well as to control the output voltage. The hysteretic control loop utilizes an adjustable dead time to set the switching frequency. The frequency is set using an external clock input pin. The DC input voltage is fed through a power path MOSFETs and is input to the controller. The controller will switch on and off at a frequency set by the external clock, producing a high frequency pulse-width modulated (PWM) signal. The PWM signal is then used to control the MOSFETs, allowing them to alternately charge and discharge the inductor and filter capacitor. This process reduces the input voltage to a lower output voltage at the desired current limit setting.The application field of NCP3102BUCK1GEVB includes AC/DC and DC/DC power designs in computer servers, computers, telecommunication systems, consumer devices, aerospace and automotive applications. The board can be used for the development of high-efficiency high-power density power supplies for any application where a high-current, low-voltage buck converter is needed. The NCP3102B Synchronous Buck Controller IC makes it possible to create power conversion designs with extremely high performance, high reliability, and low-EMI characteristics. Overall, the NCP3102BUCK1GEVB offers a complete solution for evaluating the performance of NCP3102B Synchronous Buck Controller ICs. With the board, users can test the performance and features of this controller with minimal effort and cost. With its wide operating frequency range, adjustable dead time, and various protection features, the NCP3102B Synchronous Buck Controller IC makes it ideal for a variety of AC/DC and DC/DC applications.
