Problem 2 A 1.5 volt energy source is to used to power a 5 volt, 1 amp load. A buck-boost converter is used for this application. A suitable transistor is found with an on-resistance of 35 mQ, and a Schottky diode is found with a forward drop of 0.5 volts. The on resistance of the Schottky diode may be ignored. The circuit is shown in the following figure. 1 A 100 HH 5 V Load 1.5 V DT T f,...
