Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a constant frequency hysteretic PWM controlled buck converter. In order to have good transient responses for input voltage and load current changes, a new PWM control method with inherent derivative characteristics is proposed. The proposed PWM controller consists of a comparator and a simple RC network, and it can be synchronized with an external clock signal. Since the converter operates at a constant frequency, it is easy not only to design an output filter but also to apply to multi-phase converters. The theoretical and experimental verification of the proposed method is presented and excellent steady state, dynamic performances, and transient characteristics are realized.
