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 rmoved to allow for a safer working junction
temperature.
The low side (
SW2
) device requires:
Very low R
DS(on)
to reduce conduction losses
Small Q
gls
to reduce the gate charge losses
Small C
oss
to reduce losses due to output capacitance
Small Q
rr
to reduce losses on SW
1
during its turn-on
The C
gd
/C
gs
ratio lower than V
th
/V
gg
ratio especially with low drain to source
voltage to avoid the cross conduction phenomenon;
The high side (
SW1)
device requires:
Small R
g
and L
s
to allow higher gate current peak an to limit the voltage
feedback on the gate
Small Q
g
to have a faster commutation and to reduce gate charge losses
Low R
DS(on)
to reduce the conduction losses.
