摘要：
Constant on-time (COT) control has been widely applied in industrial applications due to its fast transient response. However, the conventional COT controlled buck converter has poor output-regulation accuracy. A new control method, called improved COT (ICOT) control, that provides both high output-regulation accuracy and fast transient response for the buck converter is proposed. Circuit simulation results validate the correctness of the theoretical analysis.
