buck converter has an input voltage that varies between 10 and 15V and a load current that varies between 0.5A and 1A. The output voltage is 5V. For a switching frequency of 200kHz, determine the minimum inductance to provide for continuous current for every operating possibility
T = Tₒₙ + TₒFF
vₒ = DVₛ
L = (Vₛ-vₒ/∆lf) D
