| Abstract(in English) | The battery powered equipment demands small size, light weight and long battery operating time. The sleep mode and shut down mode is a way to reduce the power consumption. The high-speed power-up supply system enables a high frequent sleep mode system. DC-DC switching regulators generate the inrush current and overshoot voltage without a soft-start control circuit. The inrush current and the overshoot ruin the battery operating time and also the reliabilities of a coil and electronic parts. In this paper, proposes Current Mode PWM DC-DC Buck Converter which enables high-speed power-up without high inrush current and overshoot. The proposed control circuit decreased the inrush current and the output overshoot by independent of the load current, the input voltage, and the operating temperature. The power-up time, Soft-Start time, is reduced from 1/10 to 1/50 in comparison with the typical industry standard products. |
