Title:
UNMANNED PHOTOELECTRIC SOFT DRIVING CONSTANT-CURRENT CIRCUIT, INTEGRATED CIRCUIT AND CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/072000
Kind Code:
A1
Abstract:
An unmanned photoelectric soft driving constant-current circuit, an integrated circuit and a control system. The photoelectric soft driving constant-current circuit comprises a starting circuit and a constant-current circuit, uses the constant-current circuit, which is protected by a soft driving circuit, to provide a working environment subjected to automatic gain control and having a constant current and a constant voltage for a connected load, and has a higher power supply rejection ratio, thereby solving the optical efficiency problem of a change in an input voltage causing a change in the input power of the entire system, thus affecting the system efficiency.
