L6599A
Equation 13
where Qg is the gate charge of the external power MOS, R
bootstrap DMOS (150 W, typ.) and T
equals about half the switching period minus the dead time T
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
