With the widespread application of single-inductor multiple-output (SIMO) DC-DC converters, their dynamic response has much concern for domestic and foreign researchers. To explore the theoretical limit of the optimal dynamic response for the SIMO Buck converter, this paper first establishes a corresponding mathematical model according to the working principle of the converter, and then an improved differential evolution (DE) algorithm is employed to search out the solution. In addition, the suggested approach can investigate the best dynamic response with various goals, including the best self-regulation or cross-regulation. It is also possible to know the optimal dynamic response with different constraints, such as different dynamic response times and peak inductor currents. In order to completely recognize the dynamic performance of SIMO DC-DC converters, the theoretical limit exploration of optimal dynamic response based on the heuristic DE intelligent algorithm is useful. Ideally, this will direct the controller design in order to obtain an optimized dynamic response.
