TMS320LC543PZ150 Datasheet This simplified loss equation includes the terms Qgs2 and Q which are new to Power MOSFETdata sheets. oss Qnq7 is a sub element of traditional gate-source chargg2e that is included in all MOSFET data sheets. The importance of splitting this gate-source charge into two sub elements. Qgs, and Qgs2. can be seen from Fig 16. Qfiq? indicates the charge that must be supplied by the 9g~te driver between the time that the threshold voltage has been reached and the time the drain cur- rent rises to L_x at which time the drain voltage be- amax gins to change. Minimizing Qgs2 is a critical factor in reducing switching losses in Ql. Q is the charge that must be supplied to the out- put capacitance of the MOSFET during every switch- ing cycle. Figure A shows how Q is formed by the parallel combination of the voltagoes dependant (non- linear) capacitance's Ci. and Cd,, when multiplied by the power supply input dbuss voft~ge.
