  • Patent number: 8102151
    Abstract: A method of operating a Real Time Clock (RTC) in a terminal is provided. The method includes detecting a clock signal transmitted to an RTC block when the main power supply is switched off, and supplying a power to the RTC block for its operation by charging and discharging the power periodically supplied from the backup battery according to the detected clock signal. A DC/DC converter connected to a backup battery is periodically switched on and off, and a capacitor is charged and discharged using the power of the backup battery, thereby avoiding supplying power from a backup battery continuously to an RTC block. Therefore, power consumption is reduced and a duration of time for maintaining RTC data is extended.
