Schematic

Customers can choose to implement a PI filter in series with the input of a power regulator, which allows for the differential noise generated to be attenuated, allowing a noise emission regulation to be met. The filter crossover frequency is ideal for 1-MHz switching frequency, attenuating the switching frequency and the corresponding harmonics greatly. A damping capacitor is provided (C5), to damp the high-Q PI filter. For more information on filter damping, see Reference.
