Power supplies for telecommunications applications may require high currents at low voltages. Design a buck converter that has an input voltage of 3.3 V and an output voltage of 1.2 V. The output current is 6 A and the output voltage ripple must not exceed 2 percent for 500 kHz switching frequency. Determine the inductor value such that the peak-to-peak variation in inductor current does not exceed 40 percent of the average value. Determine the capacitor value required for the ripple specification given above.
