Abstract
The purpose of this paper is to present the dynamic characteristics of the digitally controlled buck-boost dc-dc converter. Furthermore, the relationship between the parameters of control circuit and the dynamic characteristics is discussed. We examine the design criterion to improve the dynamic characteristics. As a result, it is revealed that the wide range of input voltage is realized by setting not only the appropriate filter but also the suitable gain in the digitally controlled buck-boost dc-dc converter.
