N2 - A new, small and efficient voltage regulator realized using a resonant switched capacitor converter (RSCC) technology is introduced. Voltage regulation is implemented by means of simple digital pulse density modulation (PDM). It displays an ideal transient response with a zero-order response to all disturbance types. The newly developed RSCC acts as a gyrator with a wide range of voltage conversion ratios (below as well as above unity) with constant efficiency characteristics for the entire operation range. The operation of the voltage regulator is verified on a 20W experimental prototype, demonstrating ideal transient recovery without over/undershoots in response to load and line transients. Simple design guidelines for the voltage regulation system are provided and verified by experiments.
