This circuit is used to convert a larger positive input voltage to a lower positive output, using an LT1074 switching regulator. Typical waveforms are shown in Fig. 4-39B. These waveforms are based on a VIN of 20 V, VOUT of 5 V, and L of 50μH for both continuous mode (inductor current never drops to zero) with IOUT of 3A, and discontinuous mode (inductor current drops to zero during a potion of the switching cycle (IOUT =0.17 A).
