ABSTRACT:
A real-time clock (RTC) power supply device in which a power supply of a RTC is connected to a capacitor having a large capacity. The power supply of a computer system charges the capacitors by RC charging when the computer is booted. After the computer is turned off, the power stored in the capacitor is provided to the RTC, the time of power consumption by the cell is decreased, and the life of the cell is extended. The RTC power supply device comprises a first diode, a filter capacitor, a charging loop, and a battery branch.
