The NCV890204MWGEVB is a evaluation board designed for DC/DC and AC/DC (Off-Line) SMPS. This evaluation board is a three-phase boost PFC, designed to evaluate the performance of an isolated DC/DC or AC to DC converter with integrated high voltage start circuit, instantaneous power pick-up, current limit protection and frequency jitter.

NCV890204MWGEVB application field is suitable for a wide range of input voltage applications such as telecommunication systems, industrial automation equipment, welding machines, battery chargers, and other similar systems. The device enables the design of reliable, highly efficient, highly integrated three-phase AC to DC converters with a wide range of output power, low no-load consumption, and more than 85% efficiency.

The working principle of NCV890204MWGEVB evaluation board is based on the differential current sensing technique, which uses a low-cost current mirror to detect the current difference in each half of the power stage. This technique can be used to accurately measure the average output current of the power stage. The difference of the two current mirrors is then sent to the control IC and used to regulate the operation of the power stage. The differential current sensing technique is an energy saving technique that minimizes the voltage droop due to load transients during normal operation.

The NCV890204MWGEVB evaluation board has several advantages over traditional DC/DC or AC to DC SMPS designs. One advantage is that it offers better power factor and transient response and more efficient power delivery compared to conventional designs. Another advantage is that the circuit topology allows for easy design and implementation, allowing the designer to optimize the power stage for different applications. Lastly, it features the integrated start up circuit which eliminates the need for additional start up capacitors or components typically needed for traditional designs.

In conclusion, the NCV890204MWGEVB evaluation board is an ideal solution for the design of reliable, highly efficient, and highly integrated three-phase AC or DC/DC power converters. The board features the differential current sensing technique, which allows for the diagnosis of current flows within the power stage. Additionally, it also features the start-up circuit that eliminates the need for additional start-up capacitors or components. With the combination of these features, it is clear that the NCV890204MWGEVB evaluation board is an excellent choice for designers looking to achieve maximum efficiency in their power conversion applications.
