Mosfet shoot through
WebDifficulties Identifying Shoot Through Shoot through is difficult to identify unless it is so serious that the efficiency of the synchronous buck converter is significantly decreased or … Webcan result in overshoots large enough to inadvertently turn on devices, creating damaging shoot through events, increase loss with unintended turn-off glitches or corrupting fault signals to trigger false events. This interference can be reduced by minimizing copper overlaps between nets that have large voltage swings, such as the switch node.
