The LED-261560 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- 261560 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.
