Abstract
A time multiplexing circuit applied to a DC-DC converting system including first to third NOR gates, first and second inverters, first and second D-type flip-flops, a NAND gate, an OR gate and an AND gate. The first NOR gate and second NOR gate receive the first and second pulse-width modulation signals respectively and output a boost state request signal and a buck-boost state request signal respectively. The first D-type flip-flop outputs a first time multiplex output signal and a first reverse time multiplex output signal. The second D-type flip-flop outputs a second time multiplex output signal and a second reverse time multiplex output signal. The third NOR gate outputs another first time multiplex output signal. The NAND gate outputs another second time multiplex output signal. The OR gate outputs a first reverse output signal. The AND gate outputs a second reverse output signal.
