Abstract

In this paper, a digitally controlled Single Input Dual Output (SIDO) buck converter with Phase Sequence Interchange (PSI) scheme for reducing transient cross-regulation is proposed. The PSI scheme is especially designed to solve cross-regulation problem that is usually seen when load steps up in a voltage-mode SIDO buck converter operating in continuous conduction mode (CCM). In addition, a discharging path is employed to reduce cross-regulation during load drop. The digital control of the proposed scheme is implemented and verified by the FPGA. Experimental results show that the suppression of the cross-regulation is comparable to the other state-of-the-art.
