For example: using a power MOSFET with a to
ta
l gate charge of 30 n
C the drop on the
bootstrap DMOS is a
bout 1 V
, if the T
charge
is 5
s. In fact
:
Equation 3
V
drop
has to be taken into account when
the voltage drop on C
BOOT
is calculated: if this drop
is too high, or the circuit topology doesn’t allo
w a suf
ficient charging time, an external diode
can be used.
