The LED-265096 driving board is designed to drive LED backlight module. It is a constant frequency and current mode controller especially applied for LED arrays. In constant current LED applications, the LED-265096 provides an especially wide PWM dimming range and DC voltage dimming control feature which allow users to adjust brightness smoothly. Additional power protection feature is able to protect LED module from damage by overcurrent and overvoltage.

High dimming ratio (3000:1)

Low profile and compact design

Constant LED current

PWM/Or DC Voltage Dimming Control

Short circuit and overload protection

External power On/Off control
