Description
The NCV8842 Evaluation Boards provide a convenient way to implement and evaluate a complete practical buck regulator design. No additional components are required other than the DC input source and load. Separate boards are available for the SOIC−16 and DFN−18 versions of the device. The SOIC−16 board has an input voltage range of 7 V – 16 V and includes jumpers to set the DC output voltage to 2.5 V, 3.3 V or 5.0 V. The DFN−18 board has an input voltage range of 6 V – 16 V and is preset for a nominal output voltage of 3.3 V.
