Abstract

The invention discloses an amplifying and filtering type intelligent mobile phone charging circuit. The circuit is characterized by mainly consisting of a transformer T, an operational amplifier P, a triode VT1, a triode VT2, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a capacitor C5, a capacitor C6, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a resistor R6, a diode D1, a voltage-stabilizing diode D2 and a diode D3. The circuit is simple in structure and low in cost; the damage on a mobile phone battery can be reduced during charging, so that the normal service life of the battery is prolonged to more than 10,000 hours and by more than 25%; and therefore, the great convenience is brought for an intelligent mobile phone user, and the circuit is suitable for popularization and application.

Description

technical field [0001] The invention relates to a charging circuit, in particular to an amplifying and filtering smart phone charging circuit. Background technique [0002] Most of the mobile phones currently in use are smart phones, which are much more powerful than traditional mobile phones, and the time people use their mobile phones has also increased a lot accordingly. Most of the currently used smart phones use built-in batteries, that is, the batteries cannot be taken out. And because the smart phone is in the standby state, its background program is also running normally; and people use the mobile phone for a corresponding increase, so that the battery life of the smart phone is much shorter than that of the traditional mobile phone. It can only be used for about 20 hours, so the charging frequency is relatively high when using a smart phone, and the smart phone needs to be charged every day. [0003] However, the charging circuit currently used in smart phones is ...
