Figure 6.
Efficiency comparison @ 440 kHz
As can be clearly seen, the high-side 2 has the best efficiency in the whole current range,
because of the switching loss minimization (see (1)).
Now, let's consider the converter performance, with the same MOSFET configurations, at
two different switching frequencies: 300 kHz and 440 kHz. Increasing fSW, the converter
efficiency decreases, as some power losses increase with the frequency (switching losses,
HS/LS gate drive and LS reverse recovery losses, etc.…). Furthermore, the importance of a
high switching speed rises when the switching frequency increases. In Figure 6 and
Figure 7, the efficiency curves at 300 kHz and 440 kHz are illustrated.
