Single inductor dual output switching converter using exclusive control method

This paper proposes a single inductor dual output (SIDO) DC-DC Converter with exclusive control circuit. We propose two kinds of SIDO converter: a buck-buck and a boost-boost converter. We have simulated and experimented with exclusive control method. Dual voltage outputs are controlled exclusively, using error voltage feedback. This approach requires no current sensors and does not depend on the value of output voltage or output current. We describe circuit topologies, operation principles, simulation results and experimental results. Experimental self (load) regulation and cross regulation are 20mVpp in the buck-buck converter and 5mVpp in the boost-boost converter.
