Abstract
This article presents a proposal of current source based on a linear-assisted DC/DC converter, in which a linear voltage regulator assists a switching DC/DC converter in order to obtain a compact circuit with advantages of both alternatives; i.e., high efficiency (similar to the switching converter), and low output ripple and fast reaction to the load changes (similar to the linear regulator). In order to reduce the power dissipation in the linear regulator, it is considered as an assisted circu...
