RN5C752中文资料4ch RGB Laser Diode Driver for Display System数据手册Nisshinbo规格书

描述 Description

The RN5C752 is a laser-diode driver designed to support four-channel RGB/RGGB displays for driving laser scanning systems. By connecting photo diodes (PD), this device is capable of automatically detecting a threshold current and a light emitting current of each channel of the laser-diode drivers (LD).
