<p><P>PROBLEM TO BE SOLVED: To provide a boosting circuit which minimally suppresses a ripple of an output according to a variation of a load current. <P>SOLUTION: The boosting circuit comprises boosting parts (50, 58), clock generation parts (10, 38), a current detection part (21), and clock control parts (40, 16/26). The boosting parts (50, 58) boost input voltages and output them on the basis of fed boosting clocks. The clock generation parts (10, 38) feed the boosting clocks to the boosting parts (50, 58). The current detection part (21) detects the currents fed to the boosting parts. The clock control parts (40, 16/26) control the boosting clocks on the basis of a current amount detected by the current detection part (21). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
