The invention provides a step-down circuit and a system and device for converting a lithium battery to a dry battery. The step-down circuit comprises an operational amplifier, a control circuit, a first switch, a second switch, a first inductor, a first capacitor and a resistance proportion control circuit. The first input end of the operational amplifier is connected with reference voltage, the second input end of the operational amplifier is connected with the resistance proportion control circuit, and the output end of the operational amplifier is connected with the control circuit; the control circuit is used for controlling the first switch and the second switch; one end of the first inductor is connected with the other end of the first switch, and the other end is connected with oneend of the first capacitor, the resistance proportional control circuit and the output end of the step-down circuit; the other end of the first capacitor and the other end of the second switch are connected with the resistance proportion control circuit. The step-down circuit can output different voltages, and then the lithium battery-to-dry battery system outputs a plurality of voltages to accordwith the characteristics of dry battery voltages.
Description
technical field [0001] The application relates to the field of lithium batteries and dry batteries, in particular to step-down circuits, lithium battery-to-dry battery systems and devices. Background technique [0002] At present, the voltage of the dry battery will decrease as the capacity of the dry battery decreases, so the output voltage of the dry battery changes. However, the existing lithium battery to dry battery system can only output a fixed voltage, which cannot meet the characteristics of dry batteries. Contents of the invention [0003] This application provides a step-down circuit and a lithium battery to dry battery system to solve the problem in the prior art that the lithium battery to dry battery system can only output a fixed voltage; [0004] In order to solve the above technical problems, a technical solution adopted by this application is to provide a step-down circuit for a lithium battery to dry battery system, which includes: an operational amplif...
