Title
A fixed-frequency auto-buck-boost SIMO DC-DC converter with duty-cycle redistribution and duty-predicted current control
Abstract
This paper presents a fixed-frequency auto-buck-boost SIMO dc-dc converter with duty-cycle redistribution and duty-predicted current control. The switching sequence of the power transistors in the power stage and the controller design achieve fixed-frequency operation with an optimized duty-cycle allocation, to deal with static and dynamic unbalanced loading conditions of different channels. The proposed control scheme reduces average inductor current for reducing conduction loss and cross regulation during load transients.
