摘要
The present invention relates to an average current controller, an average current control method and a buck converter using the average current controller. The average current controller includes a first comparator for generating a high H signal, a multivibrator for generating a TAVG pulse signal by receiving a high H signal outputted from the first comparator, a timing generator for generating a signal CH_ON to charge/discharge a capacitor by using at least the TAVG pulse signal, an integrator circuit unit for charging/discharging the capacitor, a second comparator for outputting a corresponding signal, an up/down counter for increasing or decreasing a counting value and a digital/analog converter for outputting by converting an output (digital signal) of the up/down counter into an analog signal.
