"topology of dual-phase series capacitor DC-DC convertor, voltage-mode PWM controller with two feedback loops proposed to realize modulation of output voltage and series capacitor voltage... fast transient response technology overcame shortcomings of traditional PWM control... used dual-phase inductor current to simultaneously charge the load to further improve the response speed of converter... settling time of only 0.9μs, which is fastest transient responses"
