2.2 Optimizing EMI Behavior of Low-Power DCDC Converters
Low power DCDC converters are typically used in applications requiring highest efficiency in a smallest possible solution. For getting a small solution high switching frequency is used. High efficiency also means lowest switching losses. To get the lowest switching losses fast switching is required. This results in fast switching edges which generate high frequencies to take care of in the application design. How to address those new challenges regarding EMI is explained in detail using different application examples.
