Embodiment Construction

[0019] figure 1 It is a system block diagram of a fast charging device for a smart phone according to an embodiment of the present invention. Please refer to figure 1 , In this embodiment, the smart phone 20 is an iPhone as an example. The fast charging device 100 includes a fast charging source conversion unit 110 , a first connection unit 120 and a second connection unit 130 . Wherein, the first connection unit 120 may be a connector, and may be a Universal Serial Bus (USB) connector (ie, a connector with power transmission) to be inserted into the USB connection port of the motherboard 10 ( i.e. a socket with a power supply). At this time, the first connection unit 120 is coupled to the motherboard 10 to receive the system voltage Vcc of the motherboard 10 (ie, the voltage of the connection socket), where the system voltage Vcc may be the operating voltage or the standby voltage of the motherboard 10 .

[0020] On the other hand, the second connection unit 130 may be a ...

Abstract

A fast charging device for a smart phone, comprising a first connection unit, a second connection unit and a fast charging source conversion unit. The first connection unit is coupled to the connection socket equipped with a power supply to receive a system voltage. The fast charging source conversion unit is coupled to the first connection unit to receive the system voltage of the connection base, and provide the first voltage and the second voltage. Wherein, the first voltage is between 3.2-1.1 volts, the second voltage is between 2.7-0.6 volts, and the voltage difference between the first voltage and the second voltage is between 0.5-0.8 volts. The second connection unit is coupled to the smart phone and the fast charging source conversion unit to transmit the system voltage, the first voltage and the second voltage to the smart phone, and the smart phone starts the fast charging mode according to the first voltage and the second voltage , to receive system voltage for charging.

Description

technical field [0001] The present invention relates to an electronic device, and more particularly, to a fast charging device for a smart phone. Background technique [0002] With the increase in the penetration rate of mobile phones, mobile phones have undoubtedly replaced traditional indoor phones for modern people, and become the fastest and most convenient communication channel. However, mobile phones that only have basic functions such as calling, browsing the Internet and playing multimedia files are gradually unable to meet the increasingly diversified needs of consumers. In order to meet the needs of consumers, manufacturers of mobile phone products are all committed to developing smart phones with stronger functions and better expandability, thereby increasing market share. [0003] Since the smart phone has similar functions to the personal computer, the smart phone can be connected to the connecting port of the personal computer through a connecting cable, and t...
