Patent ID: 8829866

Claim:
A DC to DC converter for converting an input voltage, Vin, to an output voltage, Vout, the DC to DC converter comprising first and second converters, the first converter having a modified Buck topology including a first high-side switch, a first low-side switch, and a tank capacitor, the tank capacitor being disposed in between and in series with the first high-side switch and the first low-side switch, the first converter being configured to charge the tank capacitor when the first high-side switch is conducting, the second converter having a Buck topology including a second high-side switch and a second low-side switch, the second converter being configured to discharge the tank capacitor when the second high-side switch is conducting, wherein operation of the first and second converters is non-overlapping, and wherein the first and second converters are interconnected such that each is subjected to an effective input voltage lower than Vin.
