STD70N03L - STD70N03L-1 Power losses estimation

Appendix A Power losses estimation

Figure 19. Buck converter

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:

● Ver y low R

● Small Q

● Small C

● Small Q

● The C

to reduce conduction losses

DS(on)

to reduce the gate charge losses

to reduce losses due to output capacitance

to reduce losses on SW1 during its turn-on

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 Q

● Low R

to have a faster commutation and to reduce gate charge losses

g
