Abstract
Current-mode floating buck controllers are frequently used as LED drivers. The focus of this paper is to improve a previously introduced variable OFF time current-mode floating buck controller. The initial design is modified in order to operate in continuous conduction mode for a wider range of external components. The improved architecture is simulated and measured in comparison with the initial design.
