Abstract	This paper proposes a direct 12V-to-1V hybrid converter using a switched-capacitor-assisted (SCA) topology, featuring dual-path output current conduction to lower the inductor current. In contrast to the existing dual-path structures, the proposed topology realizes a high step-down conversion with efficiency improvement in heavy-load conditions. Besides, the converter further achieves an efficiency boost in light-load conditions using zero-voltage switching. Designed in a 180-nm SOI BCD process, the proposed converter regulates an output of 0.7∼1.3 V from a 12-V input with a peak efficiency of 92%. Under a loading current of 2A, it attains an efficiency over 84% at the 1-V output. Compared with the conventional buck, it achieves an improvement of 9.8% in peak efficiency and 13.6% in maximum-loading efficiency.
