The LED-284100 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-284100 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..
