N2 - This paper presents the analysis and design of three-state controlled transition mode for buck-boost converter. By introducing an additional state D2 to the transition mode, a significant efficiency improvement and output voltage ripple reduction are achieved due to the reduced average inductor current and inductor current ripple. Furthermore, the stability of the converter is enhanced according to the dynamic behavior analysis. A buck-boost converter operating in transition mode has been designed and implemented using AMS 0.35μm CMOS technology. Simulation results demonstrate that over 10% efficiency improvement can be achieved at heavy loading and the converter can be stabilized with a smaller compensation capacitor.
