6-Channel White LED Driver for up to 72 LEDs
BD6583MUV-A is white LED driver IC with PWM step-up DC/DC converter that can boost max 42.5V and current driver that can drive max 25mA. The wide and precision brightness can be controlled by external PWM pulse. BD6583MUV-A 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.
