| Abstract: | The feasibility of single inductor multiple output BUCK converter (SIMO) was verified by MATLAB model firstly At the same time, the method of design SIMO DCDC converter with current signals was presented initially to simplify SIMO controller design and reduce the area and quiescent current of SIMO controller. Results showed that the mathematical model was robust and the circuit realizing method was simple. The area of the triple channel SIMO is only 0.76mm^2, quiescent current 110uA, and drive strength 200mA. |
