PROBLEM TO BE SOLVED: To provide a switching power supply controller having a monitoring timer and simultaneously adjusting the operations of a plurality of switching power supply units of different types. SOLUTION: The switching power supply controller 1200 controls the plurality of switching power supply units for supplying power to a host microprocessor. The switching power supply controller 1200 includes a central process unit module 1205 having a monitoring timer configured to count down a timer unless a reset signal is received from the host microprocessor, and a microprocessor, wherein microprocessor causes an interrupt when the monitoring timer completes and provides a reset command to the host microprocessor in response to the interrup received from the monitoring timer. When the host microprocessor does not correspond to the reset command, the microprocessor powers down the plurality of switching power supply units. COPYRIGHT: (C)2010,JPO&INPIT |
