This concern applies to converters designed with a high resonance frequency (indicatively,
> 150 kHz), so that they run at high frequency also at full load. Otherwise, the converter will
run at high frequency only at light load, where the current flowing in the MOSFETs of the
half-bridge leg is lower, so that, generally, an R

bootstrap driver:
where Q

frequency of 200 kHz:
If a significant drop on the bootstrap driver is an issue, an external ultra-fast diode can be
used, thus saving the drop on the R
