SINGLE INDUCTOR VOLTAGE CONVERTER

摘要

PURPOSE: A DC voltage converter is provided to generate DC voltages which have different levels from a single input voltage by using a single inductor. CONSTITUTION: A one end of an inductor(L) is connected to a first node. The other end of the inductor is connected to a second node. A first output voltage is outputted from one end of a first capacitor. A second output voltage is outputted from one end of a second capacitor. A first switch(S1) is located between the first node and an input. A second switch(S2) is located between the second node and a first output. A third switch(S3) is located between the second node and the ground. A fourth switch(S4) is located between the first node and the second output. The first capacitor(C1) is located between the first output and the ground. The second capacitor(C2) is located between the second output and the ground.
