一种用于改善负载瞬态响应的车载12V转1.2V集成开关电容DC-DC变换器

This letter presents a 12 V-to-1.2 V switched-capacitor dc–dc converter, which has a voltage conversion ratio of 1/10 with an input voltage of 12 V, for automotive applications. The power stage comprises an eight-phase ladder converter and a 16-phase 3-to-1 converter. All power switches are designed using 5-V isolated complementary metal-oxide-semiconductor (CMOS) transistors. To improve the load ...
