一种使用低压器件实现高输入电压降压的可扩展混合调节器

This paper presents a voltage regulator topology, implemented using low-voltage devices, for converting high input voltage (>4.5 V) to low output voltages with fine-grain control (0.3 to 1 V). The topology merges a Dickson's switched-capacitor stage with a current-mode inductive buck stage, and optimizes the frequency of operations to reduce the overall passive size. The proposed two-stage hybrid ...
