The NCP3064SCBCKGEVB1 Evaluation Board was developed to evaluate the NCP3064 integrated circuit. Developed by ON Semiconductor, the device is an auxiliary supply controller designed for off-line switch-mode power supplies (SMPS) across DC/DC and AC/DC. The board is based on a peak current mode control scheme and comes integrated with a low-cost line-voltage sensing network.

Application Field

The NCP3064SCBCKGEVB Evaluation Board is designed to be used in isolated DC/DC and AC/DC applications. The board comes with all the necessary components required for use, including a voltage regulator, current-sense resistor, line voltage sensing network, bulk capacitor, and an NCP3064. The evaluation board can be used in a number of applications, such as AC-DC offline applications, boost topology for isolated outputs, forward converters, flyback converters for off-line LED driver designs, and many more.

Working Principle

The working principle of the evaluation board is based on peak current mode control. The board uses a voltage regulator, current-sense resistor, and a line-voltage sensing network to sense the input voltage and regulate the current through the NCP3064. The NCP3064 is then used to control the output voltage by regulating the input current. The NCP3064 acts like a microcontroller, and it is programmed to shut off the current in the case of an over-voltage or over-temperature condition.

The NCP3064 also features an integrated MOSFET driver, which enables it to regulate the input current to the output. The MOSFET driver also helps in improving the efficiency of the evaluation board. The board also includes a bulk capacitor to provide storage for energy when the power supply is off.

In addition, the evaluation board provides an LCD display and pushbutton control for setting up the operating parameters of the NCP3064. The board also contains a potentiometer for adjusting the output voltage, which can be adjusted manually or used with a microcontroller to automatically adjust the output voltage. This makes it easier to configure the board for different applications.

Overall, the NCP3064SCBCKGEVB1 Evaluation Board is designed to make it easier for engineers to evaluate the performance of the NCP3064 in isolated DC/DC and AC/DC applications. The board comes integrated with all the necessary components required for device operation and provides an LCD display and pushbutton control for setting up the operating parameters.
