SOLVED: The specifications for a desired buck regulator are as follows: At the input, Ein = 28 (+3, -4) V, efficiency 85%, frequency 15 KHz. For output, Eout = 20 V, Io = 1 A, peak to peak ripple 60 mV. a) Calculate the required parameters, i.e., L C for the regulator. Take Imax = 1.125 A. VL, IL, IL(0), IL(T), 0, T, t, TON, TOff, t, T, 0, On, Off. b) Choose from an electronic catalogue the appropriate semiconductor devices, i.e., the switch and diode, and also L C. c) Calculate the l
