The LED-285180 driving board is designed to drive LED backlight module. It is a constant frequency and current mode controller applied to drive various LED rails. In constant current LED applications, the LED-285180 provides wide dimming feature through PWM or DC voltage control to allow users to adjust brightness smoothly. Additional power protection feature protects LED module from damage by overcurrent and overvoltage.

Applicable to 8 LED Strings

Low profile and compact design

Costant LED Current (80mA)/ Per String

PWM/or DC Dimming Control

Short circuit and overload protection

Output Voltage 41V~50V
