6.3.6 Electromagnetic Compatibility (EMC) Considerations

UCC33410-Q1 devices use spread spectrum modulation algorithm for the internal oscillator and advanced internal layout scheme to minimize radiated emissions at the system level.

Many applications in harsh industrial environment are sensitive to disturbances such as electrostatic discharge (ESD), electrical fast transient (EFT), surge and electromagnetic emissions. These electromagnetic disturbances are regulated by international standards such as IEC 61000-4-x , CISPR 32 and CISPR-25. Although system-level performance and reliability depends, to a large extent, on the application board design and layout, the device incorporates many chip-level design improvements for overall system robustness.
