4-Channel White LED Driver with Integrated FET for up to 24 LEDs - BD6586MUV

BD6586MUV is white LED driver IC with PWM step-up DC/DC converter that can boost max 24V and current driver that can drive max 25mA. The wide and precision brightness can be controlled by external PWM pulse. BD6586MUV 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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
