DC-DC DC-DC Quasi-current-mode Hysteretic Control Method for Switching DC-DC Converter Quasi Inductor Current Emulator for Switching DC-DC Converter and Hysteretic Converter using thereof

摘要

The present invention relates to a doctor inductor current and hysteresis emulator tick switching DC-DC converter of the pseudo current mode hysteresis control method, the switching DC-DC converter. To this end, if the feedback output voltage input to the hysteresis comparator tick touches the boundary voltage of the hysteresis window, characterized in that the doctor is sensing a voltage of the inductor current emulator initialization, the pseudo current mode hysteresis using a hysteresis control method tick switching DC- DC converter is provided. According to this effect, the output voltage (V _O) which rapid recovery is generated in the transient response.
