98.1%-Efficiency Hysteretic-Current-Mode Noninverting Buck–Boost DC-DC Converter With Smooth Mode Transition

A noninverting buck-boost dc-dc converter can work in buck, boost, or buck-boost mode. Hence, it provides a good solution when the input voltage may be higher or lower than the output voltage. However, a buck-boost converter requires four power transistors, rather than two. Therefore, its efficiency...
