Skottky Diode, D2
In the non-synchronous scheme a flyback diode is
required to provide a current path to the output when the
high side power MOSFET, Q1, is switched off. The crit-
ical criteria for selecting D2 is that it must have low

forward voltage drop. The product of forward voltage
drop and condition current is a primary source of power
dissipation in the convertor. The Schottky diode selected
is the International Rectifier 32CTQ030 which has 0.4V
of forward voltage drop at 15A.
