Title: Dc/dc converter
Inventor: MURASE MINORU
IPC: H02M3/145
Filed: 2002-01-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a DC/DC converter in which a rush current is lowered.  <P>SOLUTION: When a charge pump circuit 1 is not operated in a state in which a power source is turned on, MOS transistors Q5 to Q7 of a preliminarily charging circuit 6 are turned on to charge the capacitor C1 and an output capacitor CV1. Meanwhile, at an operation start of the pump circuit 1, a contact of a changeover switch SW1 is switched reverse to a state as shown, and a MOS transistor Q3A is used instead of a MOS transistor Q3. Since the size of the transistor Q3A is smaller than that of the transistor Q3, the current of the transistor can be reduced. Thus, at the start of the circuit 1, a rush current of the capacitor C1 can be alleviated.  <P>COPYRIGHT: (C)2003,JPO
