LP8866-Q1 Typical Design Guidelines to Achieve CISPR 25 Class 5 Conducted and Radiated Emissions Compliance

Electromagnetic Compatibility (EMC) is of increasing importance as the number of electronic/electrical components used in vehicles increases. The radio disturbances produced by components/modules in a vehicle should be mitigated to provide protection for receivers installed in the same vehicle. This application report describes a typical design using LP8866-Q1 which can conform to the CISPR 25, class 5 conducted and radiated emissions limits.
