[ Product description ]

BD6142AMUV is white LED driver IC with PWM step-up DC/DC converter that can boost max 41V and current driver that can drive max 30mA. The wide and precision brightness can be controlled by external PWM pulse.
BD6142AMUV 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 panel.
Small package is suited for saving space.
