STD50N03L - STD50N03L-1 Buck converter

Appendix A Buck converter

Figure 18. 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 R

■ 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;

to reduce conduction losses

DS(on)

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 R

to reduce the conduction losses.
