600 V CoolMOS™ CFD7: How big is the drawback due to the mid-field Qoss?(KA-13192)
We recommend not to operate CoolMOS™ CFD7 in full ZVS mode, but to switch it on at 25V. The Eoss difference at 25V compared to our competition is more than compensated by the best-in-class Eoff of CFD7; the Eon losses at this voltage level are negligible. In addition, the recirculating current is reduced to a minimum and leads to decreasing losses.
