11 / 47 page  AN4192 High-side MOSFET selection Doc ID 023820 Rev 1 11/47 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. Figure 7. Efficiency @ 300 kHz Table 1.
