A power-tracking embedded buck–boost converter with a fast dynamic voltage scaling (F-DVS) function is proposed to power the system-on-a-chip (SoC) system. To meet the power request of the SoC for different operation functions, fast up/down-tracking is implemented to achieve the F-DVS function. Recycling energy is also derived to minimize power dissipation during the down-tracking period. In addition,...

This paper presents a buck-boost converter with high efficiency and small output ripple to extend the battery life of portable devices. Besides, the hybrid buck-boost feedforward (HBBFF) technique is integrated in this converter to achieve fast line response. The new control topology minimizes the switching and conduction losses at the same time even when four switches are used. Therefore, over a...

This paper presents a high-efficiency and smooth-transition buck-boost (BB) converter to extend the battery life of portable devices. Owing to the usage of four switches, the BB control topology needs to minimize the switching and conduction losses at the same time. Therefore, over a wide input voltage range, the proposed BB converter consumes minimum switching loss like the basic operation of buck...
