Appendix A
The power losses associated with the FETs in a Synchronous Buck converter can be
estimated using the equations shown in the table below. The formulas give a good
approximation, for the sake of performance comparison, of how different pairs of devices
affect the converter efficiency. However a very important parameter, the wotking
temperature, is not considered. The real device behavior is really dependent on how the
heat generated inside the devices is removed to allow for a safer working junction
temperature.
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 Lg 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
