Abstract: This paper proposes a single inductor dual output (SIDO) DC-DC Converter with exclusive control circuit. We propose two kinds of converter: a buck-buck and a boost-boost converter. Multiple voltage outputs are controlled exclusively, using error voltage feedback. This approach requires few additional components (a switch, a diode and a comparator), requires no current sensors and does not depend on the value of output voltage or output current. We describe circuit topologies, operation principles and simulation results.
