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.
