Abstract
A down converter for converting an input DC voltage (Vin) into a lower output DC voltage (Vout). The down converter has on the primary side () an LC series resonance circuit () that can be connected via a first switch (S) to the input voltage (Vin) and via a second switch (S) to ground. On the secondary side (), an output switch (S) and an output capacitor (C) are each connected in parallel to the DC voltage output (Vout) and connected to each other through an inductor (L). The output switch (S) is connected via a diode (Dr) to the input voltage (Vin) so as to divert voltage overshoots.
