US Patent 10374511 Switched capacitor DC-to-DC converter and power conversion control methods

A scalable controller circuit that provides faster and simpler regulation of a DC-to-DC converter is provided. Unlike such prior techniques, preferred embodiments do not require any threshold-level generation circuitry or analog compensation circuitry. Preferred embodiments implement a simple control law that requires only a few digital gates. Preferred embodiments can therefore significantly reduce the overhead power consumption and area of the controller in DC-to-DC converters to new levels.
