LED constant current driver board LED-283265 (130mA) DC dimming

The LED constant current driver board LED-283265 is designed to drive LED backlight module. It is a constant frequency and current mode controller applied to drive various LED strings. In constant current LED applications, the LED-283265 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.
