PROBLEM TO BE SOLVED: To reduce power consumption of a switching regulator. SOLUTION: A buffer drive circuit 41 drives a PMOS transistor QP2 and an NMOS transistor QN2 independently, and a PMOS transistor QP3 and an NMOS transistor QN3 independently. Accordingly, the PMOS transistor QP2 and the NMOS transistor QN2 will not turn on at the same time nor the PMOS transistor QP3 and the NMOS transistor QN3 will not turn on at the same time. This does not allow penetration current to flow, thus reducing power consumption of the switching regulator. COPYRIGHT: (C)2008,JPO&INPIT
