NCP5425SOEVB

The NCP5425SOEVB is a buck controller evaluation board which can be used to evaluate the performance and functionality of NCP5425 which is a highly flexible dual buck controller. The NCP5425 consists of an internal gate drivers that can be used with two input power supplies and one or two outputs in multiple configurations. This IC contains all the circuitry required for two independent synchronous dual NFET buck regulators utilising a feed forward voltage mode control method. The NCP5425SOEVB is a 4.0 inch by 4.0 inch, two layer printed circuit board with an actual circuit area of 2.5 inch by 2.3 inch. This evaluation board evaluate the performance NCP5425, configured to generate a 1.5V and 1.8V output from a single input voltage (5.0V). Each output is capable of delivering 1A.
