Webence (EMI). In a synchronous buck converter, fast-switching field-effect transistors (FETs) can experience significant voltage overshoots and ringing on the switch node. The magnitude of the ringing is a function of the high-side MOSFET’s switching speed and the stray inductances in the layout and FET package. WebRF EMI from external sources is commonly received in two ways: As an ESD event that conducts a broadband pulse into a system. As conducted EMI through a power input, which can span up to sub-GHz frequencies. Typical ESD waveform induced on an interconnect. This narrow pulse will have broad bandwidth that extends into RF frequencies and excite …
