Figure 10 shows the upper gate drive supplied by a direct
connection to V
CC
. This option should only be used in
converter systems where the main input voltage is +5V
DC
or
less. The peak upper gate-to-source voltage is approximately
V
CC
less the input supply. For +5V main power and +12V
DC
for the bias, the gate-to-source voltage of Q
1
is 7V. A logic-
level MOSFET is a good choice for Q
1
and a logic-level
MOSFET can be used for Q
2
if its absolute gate-to-source
voltage rating exceeds the maximum voltage applied to V
CC
.
Schottky Selection
Rectifier D
2
is a clamp that catches the negative inductor
swing during the dead time between turning off the lower
MOSFET and turning on the upper MOSFET. The diode
must be a Schottky type to prevent the lossy parasitic
MOSFET body diode from conducting. It is acceptable to
omit the diode and let the body diode of the lower MOSFET
clamp the negative inductor swing, but efficiency will drop
one or two percent as a result. The diode’s rated reverse
breakdown voltage must be greater than the maximum
input voltage.
