ISOW7841-Slide10

The emissions benefit is discussed on this slide, including what causes emissions and how the emissions are reduced in the ISOW7841. In discrete solutions, such as the one shown on the left side, radiated emissions are controlled by utilizing high inductance magnetic-core transformers, allowing lower switching frequencies and reducing emissions. Whereas the integration of the power transformers requires smaller devices and fewer turns, enabling a higher switching frequency. Integration also places transformers close together, causing parasitic capacitance between the two sides which can cause radiated emissions. This is a challenge for all integrated solutions.
