Abstract
This paper proposes a new SIDO (Single Inductor Dual Output) DC-DC switching converter with hysteretic
control. It requires few additional components (a comparator and a latch) to control two DC-DC converters with
single inductor, buck and buck converters or boost and boost converters.. We investigated exclusive control method which converts only one converter except another converter for some clock periods. The architecture of exclusive control method is to compare two errors of the output voltage and to decide the converter that is controlled next time. This control method has the merit not to depend on either output voltage or output current. We describe circuit topologies, operation principles and simulation results.
