Parameter determination for switching power supply circuit, the parameter determination for linear regulators, switching power supply circuit system for parameter determination, development support system of the switching power supply circuit, as well as, its program and recording medium
PROBLEM TO BE SOLVED: To achieve a semiconductor integrated circuit for a power supply which is comparatively small in circuit scale and can support development of a power supply circuit set in an more appropriate parameter.;SOLUTION: The power supply platform IC3 is connected to an electronic circuit IC instead of the power supply circuit for deciding the parameter of the power supply circuit which supplies electric power to the load of the electric circuit IC, and constitutes a power supply circuit P1 for deciding on the parameter. The platform is equipped with a transistor array 12, comprising a plurality of transistors which can be operated as a switching transistor, and a control circuit 16 which controls the size of the transistor operating as the switching transistor, by selecting a transistor operating as the switching transistor from among the plurality of transistors. The control circuit 16 changes the size of the switching transistor as the parameter of the power supply circuit, corresponding to the instructions from the outside.;COPYRIGHT: (C)2007,JPO&INPIT
