Mosfet maximum switching frequency

WebThe Mosfet input capacitance (Ciss) is frequently misused as the load represented by a power mosfet to the gate driver IC. In reality, the effective input capacitance of a Mosfet (Ceff) is much higher, and must be derived from the manufacturers’ published total gate charge (Qg) information. Even the speci-fied maximum values of the gate ... WebMar 2, 2006 · MOSFET. Therefore switching can be very fast, resulting in low switching losses.
