1 Passing CISPR-25 Radiated and Conduction Emissions Using the TPS65035x-Q1

This application note provides a summary of the CISPR-25 Conducted and Radiated Emissions test results using the TPS650350-Q1 Power Management Integrated Circuit (PMIC) for automotive camera applications. This device is capable of passing CISPR-25 and other automotive electromagnetic-compatibility (EMC) test specifications. Similar results can be achieved using other devices in the TPS65035x-Q1 family. Due to an advanced spread spectrum clocking (SSC) feature, these devices can pass EMC tests without needing a fully-optimized layout, allowing for more flexible component placement and routing as required by the camera application.
