  • Publication number: 20130275786
    Abstract: A main processor of mobile phone changes from power saving state to active state for changing display in response to a sub processor for sensors, the main processor returning to the power saving state after changing the display. The main processor changes from power saving state to active state for storing information from the sub processor, the main processor returning to the power saving state after the storing function. The main processor selects the stored display data on the basis of the information from the sub processor to change display. The main processor receives and stores information from the sub processor in the boot up process or before finishing the operation. The sub processor is in the active state so as to control the sensor even in a case where the main processor is in the power saving state.

  • Patent number: 8558529
    Abstract: An output monitoring comparator outputs an ON signal when an output voltage becomes lower than a reference voltage. A pulse modulator generates a pulse signal at a predetermined level, an ON time-period from when the ON signal is outputted. A driver circuit alternately turns ON, after a dead time, a switching transistor and a synchronous rectification transistor, based on the pulse signal. A light load mode detector compares a switching voltage at a connection point of the switching transistor and the synchronous rectification transistor, and ground potential, and at timing at which the ON signal is outputted from the output monitoring comparator, when the switching voltage is higher than the ground potential, nullifies the ON signal.
