2 - A buck converter has an input voltage that varies between 20 and 25 V and a load current that varies between 1.5 A and 2 A. The output voltage is 15 V. For a switching frequency of 100 kHz, a) determine the minimum inductance (Lmin) to be in continuous conduction mode (CCM) for every operating possibility, b) For LIR = 40%, determine the minimum capacitance to have less than 1% output voltage ripple. c) Repeat part (b), if the ESR of the capacitor is given as = (50 106 )/ where C is in Farads
