ET6037中文资料18CH 128 Step Dimming数据手册ETEK规格书

描述 Description

ET6037 is designed for LED displays with 128 steps linear current adjustable, built-in 18 independent low-resistance color LED driver channel, each can provide 2~45Ma (register fixbrit_ledn data=52H) constant current. ET6037 uses the I2C BUS structure, it can adjust arbitrary channel’s current by the code set. The total 128 steps current’s range is 0%~190%. OUT0~OUT17, every three channel share one enable switch. The RGB LED’s brightness can be changed by controlling the enable switch signal.

特性 Features

• 18 constant-current output channels

• Constant output current invariant to load voltage change

• Excellent output current accuracy

• Output current adjusted through an external resistor

• Each channel can be adjusted its current
-- Scope：0%~190%, 128 steps, while register fixbrit_ledn data=52H current =100%
