Title:
UNMANNED ELECTRO-OPTIC DRIVE CONSTANT CURRENT CIRCUIT, INTEGRATED CIRCUIT AND CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/071940
Kind Code:
A1
Abstract:
Provided is an unmanned electro-optic driving constant current circuit, an integrated circuit and a control system. The electro-optic driving constant current circuit comprises a constant current circuit and a mirror circuit. A constant current circuit is used to provide a working environment featured with automatic gain control, constant current and constant voltage for a load with an isolation function connected to the constant current circuit, so that the constant current circuit has a higher power supply rejection ratio, which solves the problem that changes in input voltage can cause changes in the input power of the entire system, thereby affecting the efficiency of the system.
