白色背光LED驱动器,用于中到大型液晶面板(开关稳压器型) White Backlight LED Driver for Medium to Large LCD Panels Switching Regulator Type
● Description
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.Small package type is suited for saving space.
