) ⎛ Qgd +⎜I × × Vin × ig ⎝ + (Qg × Vg × f ) + ⎛ Qoss × Vin × f ⎞ ⎝ 2 ⎠ ⎞ ⎞ ⎛ Qgs 2 f⎟ + ⎜ I × × Vin × f ⎟ ig ⎠ ⎝ ⎠ 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 dr.
