Key Features

  • s 2 Qgd +I× × Vin × f  +  I × × Vin × ig ig    + (Qg × Vg × f ) +  Qoss × Vin × f   2   f  This simplified loss equation includes the terms Qgs2 and Qoss which are new to Power MOSFET data sheets. Qgs2 is a sub element of traditional gate-source charge that is included in all MOSFET data sheets. The importance of splitting this gate-source charge into two sub elements, Qgs1 and Qgs2, can be seen from Fig 16. Qgs2 indicates the charge that must be supplied by the gate driver betwee.
