Title:
RTC CLOCK POWER SUPPLY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/161430
Kind Code:
A1
Abstract:
An RTC clock power supply circuit, comprising a power supply source (Vc), the RTC clock power supply circuit also comprising a voltage divider circuit (1) and an emitter follower circuit (2); an input end of the voltage divider circuit (1) is connected to the power supply source (Vc), conveying the power supply voltage (Vc) after division to an input end of the emitter follower circuit (2), and an output end of the emitter follower circuit (2) being connected to a power supply pin (31) of the RTC clock (3); by means of arranging the voltage divider circuit (1) and the emitter follower circuit (2) between the power supply source (Vc) and the power supply pin (31), a stable working voltage is provided to the RTC clock, and the voltage of the power supply source (Vc) and the power supply pin (31) of the RTC clock (3) match.
