Abstract

The invention discloses a switch-type peripheral charging circuit and a charging system. The switch-type peripheral charging circuit comprises a switch-type charging chip. The input end of the switch-type charging chip is connected with a direct-current power supply, the output end of the switch-type charging chip is connected with a battery to be charged, and the switch-type charging chip is usedfor carrying out constant-current charging on the battery to be charged when the voltage of the battery to be charged is smaller than a constant-voltage threshold voltage of the switch-type chargingchip. And when the voltage of the battery to be charged is greater than or equal to the constant-voltage threshold voltage of the switch type charging chip, constant-voltage charging is performed on the battery to be charged. The battery to be charged is charged by adopting the switch type charging chip so that a charging heat loss can be effectively reduced, and the charging efficiency of the battery to be charged can be effectively improved. In addition, the phenomenon that the battery to be charged is overcharged due to the fact that the battery to be charged is fully charged can be avoided, and therefore the use loss of the battery to be charged is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of circuit design, in particular to a switch-type peripheral charging circuit and a charging system. Background technique [0002] As the demand for wireless portable products in the market becomes stronger and stronger, the types of wireless portable products become more and more abundant, and users use more and more wireless portable products. Since it is not convenient for the user to carry a power source when traveling, it is inconvenient to design wireless portable products as a way of connecting the power supply with wires, and most of the wireless portable products are designed to have a rechargeable battery for independent power supply, resulting in wireless portable products. There is an increasing demand for charging efficiency in large-capacity rechargeable batteries. [0003] At present, circuit designers use linear low dropout regulator (LDO) charging chips to charge b...
