This paper presents a novel switching topology for SIDO buck converters aiming to achieve charge recycling during sink/source operation. Two switching sequence options have been demonstrated for low load current (DCM) and high load current (CCM) profiles. Simulation results show that the proposed architecture can achieve sink/source operation by re-using the charge stored in the output capacitors with continuous conduction through the inductor, demonstrating that this topology promises to be a convenient solution for SIDO/SIMO switching converters where sink/source operation and high power efficiency are essential.
