... A bootstrap circuitry is needed to supply the high voltage section. This function is normally accomplished by a high voltage fast recovery diode (fig. 8a). In the L6388 a patented integrated structure replaces the external di- ode realized by a high voltage DMOS, driven synchronously with the low side driver (LVG), with in series a diode, as shown in fig ...

... L6388 has to be long enough to charge the capacitor. The bootstrap driver introduces a voltage drop due to the DMOS RDSON (typical value: 125 Ohm). At low fre- quency this drop can be neglected. Anyway increasing the frequency it must be taken in to account. The following equation is useful to compute the drop on the bootstrap DMOS: ...
