The results of the step-down switched capacitor voltage converter development have been presented. The maximal operating frequency of the proposed converter is 140 MHz, while providing the conversion efficiency 93%. The digital feedback control system, executing the operating frequency modulation, functioning in conditions of the converter input voltage reduction depending on the load current as well as adjusting the conversion ratio to provide the necessary level of the output voltage, has been provided. The converter has been designed according to 32nm CMOS technology.
