BD8109FM NEW
[ Product description ]
BD8109FM is white LED driver IC with buck-boost DC / DC converter and current driver. The wide and precision brightness can be controlled by external PWM pulse. They have very accurate current drivers, and it has few current errors between each strings. So, it will be helpful to reduce brightness spots on the LCD.
