4 Appendix A

  • The low side (SW2) device requires:
  • Very low RDS(on) to reduce conduction losses
  • Small Qgls to reduce the gate charge losses
  • Small Coss to reduce losses due to output capacitance
  • Small Qrr to reduce losses on SW1 during its turn-on
  • The Cgd/Cgs ratio lower than Vth/Vgg ratio especially with low drain to source
  • voltage to avoid the cross conduction phenomenon;
  • The high side (SW1) device requires:
  • Small Rg and Ls to allow higher gate current peak and to limit the voltage feedback on the gate
  • Small Qg to have a faster commutation and to reduce gate charge losses
  • Low RDS(on) to reduce the conduction losses.
