Abstract :
This paper presents a current-mode control non-inverting buck-boost converter. The proposed circuit is controlled by the current mode and operated in three operation modes which are buck, buck-boost, and boost mode. The operation mode is automatically determined by the ratio between the input and output voltages. The proposed circuit is simulated by HSPICE with 0.5 ¿m standard CMOS parameters. Its input voltage range is 2.5-5 V, and the output voltage range is 1.5-5 V. The maximum efficiency is 92% when it operates in buck mode.
