What is special about the DC-DC Switching Regulator that makes it an option?
The DC-DC Switching Regulator is an optional add-on to the NWSAMD product that produces a more efficient power source for the product. The linear regulator included by default converts the input voltage to a lower voltage for safe use by the product. However, it does this very inefficiently when used with high input voltages due to the lack of power conversion. A switching regulator is based on the principles of AC efficiency by converting the DC to a form of AC and then back again after the power has been converted. As such, a switching regulator can be considered to be more of a power regulator than a voltage regulator. The power output by a switching regulator is approximately the same as the power input. With a linear regulator, the current output is approximately the same as the current input. In all cases the voltage output is lower than the voltage input. Because power equals current times voltage, there is a substantial benefit at higher input voltages. The following tables sho
