LED backlight driver board LED-244130 (30mA) DC dimming

The LED backlight driver board LED-244130 is designed to drive LED backlight in TFT LCD module. It is a constant frequency and current mode controller applied to drive various LED strings. In constant current LED applications, the LED-244130 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.
