Abstract :
A family of single-inductor multiple-output switching converters that provide both positive and negative output voltages is presented. With time multiplexing control, both step-up and step-down bipolar outputs could be achieved. Technical considerations on control loop design and implementing synchronous rectification for a single chip converter are discussed. Simulation results are presented to show the validity of the proposed converters
