[ Product description ]

BD6581GU is white LED driver IC with PWM step-up DC/DC converter that can boost maximum 42.5V and current driver that can drive maximum 25mA. The wide and precision brightness can be controlled by external PWM pulse.
BD6581GU has 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.
Small package type is suited for saving space.
