Key Features

  • primarily in Q1. Ploss = (Irms × Rds(on ) ) 2 ⎛ ⎞ ⎛ Qgs 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 t.
