ET6034A中文资料LED灯效驱动数据手册ETEK规格书

描述 Description

 
ET6034A is designed for LED displays with 128 steps linear current adjustable, built-in 16 independent
low-resistance color LED driver channel, each can provide 2~45mA（register fixbrit_ledn data=52H） constant current. ET6034A uses the I2C BUS structure, it can adjust arbitrary channel’s current by the code set. The total128 steps current’s range is 0%~190%. OUT0~OUT5,OUT10~OUT15,every three channel share one enable switch. The RGB LED’s brightness can be changed by controlling the enable switch signal.
