| Abstract(in English) | Recently, not only note book computer, but also mobile device, DTV, game device are using CPU, GPU and fast speed memory. So, DC-DC is required to fast load transient response. Conventional linear control such voltage mode or current mode control has limitation of response speed due to delay from PWM and compensation circuit. Non-linear control such hysteretic control has been attractive due to its ultra fast response capability. Hysteretic control has some disadvantage such that can not operates with ceramic capacitor due to too small ripple at output. However, ripple injection method and its frequency domain analysis could make optimal design. Now advanced hysteretic control become very popular and widely used in the world. |
