Buck converter: power losses estimation 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 working 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 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.
