Equation 13
where Qg is the gate charge of the external power MOS, R(DS)ON is the on-resistance of the
bootstrap DMOS (150 W, typ.) and Tcharge is the ON-time of the bootstrap driver, which
equals about half the switching period minus the dead time TD. For example, using a
MOSFET with a total gate charge of 30nC, the drop on the bootstrap driver is about 3 V at a
switching frequency of 200 kHz:
Equation 14
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(DS)ON of the internal DMOS.
