FDMF6704 Rev. G
Switch Node Ringing Suppression
Fairchild's DrMOS products have proprietary feature* that minimizes the peak overshoot and ringing voltage on the switch node
(VSWH) output, without the need of external snubbers. The following pictures show the waveforms of an FDMF6704 DrMOS part and
a competitor's part tested without snubbing. The tests were done in the same test circuit, under the same operating conditions.
