A DC-DC buck converter is required to produce a 5V output from an input voltage that varies over the range 10 – 40V. (a) If the minimum output load is 5 W and the switching frequency is 50 kHz, calculate the smallest value of filter inductor that will achieve continuous switching under all input voltage conditions. (43.75 ?H) (b) Determine the size of the output filter capacitor required to achieve a worst-case output voltage ripple of 50 mV. (100 ?F) (c) If the output load is changed to a resistor that draws 2 W at 5 V, calculate the output voltage at an input voltage of 40 V, if the duty cycle does not change. (7.62 V) (d) What duty cycle is required to return the output voltage to 5 V under the conditions of part (c). (0.0791)
