being more widely used in various electronic devices. As the display is one of the modules that consumes the largest portion of the power in electronic devices, displays must be designed to operate with a higher efficiency to improve a battery longevity. As a means of supplying power to such displays, DC-DC converters and their performance are important. Along with high efficiency, a DC-DC converter should provide quiet supply voltages for the display to avoid light fluctuation [1]. For this reason, many devices use two separate DC-DC converters, boost and inverting buck-boost converters, to generate a positive (Vop) and a negative (Von) output voltage, respectively [2], as shown in top-left of Fig. 11.6.1. Although this structure is advantageous for making quiet output voltages owing to its two-phase operation, it is not cost effective because it uses two inductors. In the single-inductor bipolar-output (SIBO) converter shown in top-right of Fig.
