Title: Switching power circuit and electronic equipment using the same
Inventor: KANAMORI ATSUSHI
IPC: H02M3/155
Filed: 2003-01-24
Abstract: <P>PROBLEM TO BE SOLVED: To realize a switching power circuit having high power conversion efficiency.  <P>SOLUTION: A pulse width control circuit 33, provided in a drive circuit 28, gives instructions to an OFF-drive circuit 32 about operation for a period shorter than the period for which a drive control signal Vdrv is inactive. Accordingly, when the drive control signal Vdrv becomes inactive, the OFF-drive circuit 32 starts operation, and draws a current out of the base of a switching element 11 and turns off the switching element 11. Further, the OFF-drive circuit 32 stops operation before the drive control signal Vdrv becomes active. Thus, power consumption can be reduced, as compared with the cases where the OFF-drive circuit 32 continues to operate for the inactive period, and the power conversion efficiency can be enhanced.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
