  ABSTRACT: This paper presents the relationship between the dynamic characteristics and sampling frequency of digitally controlled dc-dc converter with a novel control method. In the proposed method, the calculation process of P and I-D controls is parallel. The sampling interval and points for I-D control are same to the conventional method. However, the sampling point for P control is quickly. The AD converter can sample the output voltage during the short interval because the calculation process of P control is very simple and to important for transient response. The only sample data near the turn-off timing of PWM pulse is used. The simulation and experiment results of the output voltage against the step change of the load and changing the P control sampling frequency are discussed. As a result, it is revealed experimentally that the good transient response is obtained.
