General 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 2~45mAregister 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.

 

 

Features
 

 16 constant-current output channels

 Constant output current invariant to load voltage change

 Excellent output current accuracy:

 Normal between channels: <±1.5% (typical); normal between ICs: <±3% (typical)

 Output current adjusted through an external resistor

● Each channel can be adjusted its current 0%~190%, 128 steps

Constant output current range:245mA;(VDD=5V:2~45mA; VDD=3.3V:2~30mA )

● I2C interface, four chip-address

● RGB LED brightness adjustment function of any color

 Soft shutdown, shutdown current is less than 5uA@5V, 3uA@3.3V

 Supply voltage2.7V5.5VTYP.

 Package: QFN24
