The letter proposes to model cross-regulation in a dual-output switched capacitor converter (SCC) by three equivalent resistances connected in delta circuit. It is shown that as opposed to linear equivalent (output) resistance of single-output SCCs, these resistances are voltage-controlled. The obtained analytical expressions have been verified by simulations and give correct results even if the output voltages change in wide range. The proposed analysis paves the way for modelling cross-regulation in complex SCCs with multiple topologies and can be useful in studies of crosstalk through parasitic capacitances on chip.
