CIRCUITS AND METHODS PROVIDING THREE-LEVEL SIGNALS AT A SYNCHRONOUS BUCK CONVERTER |
| 摘要 |
A circuit including: a three-level buck converter having: a plurality of input switches and an inductor configured to receive a voltage from the plurality of input switches, the plurality of input switches coupled with a first capacitor and configured to charge and discharge the first capacitor; a second capacitor at an output of the buck converter; and a switched capacitor at an input node of the inductor, wherein the switched capacitor is smaller than either the first capacitor or the second capacitor. |
