6-Channel White LED Driver with Integrated FET for up to 60 LEDs - BD6590MUV

BD6590MUV is white LED driver IC with PWM step-up DC/DC converter that can boost max 40V and current driver that can drive max 30mA. The wide and precision brightness can be controlled by external PWM pulse. BD6590MUV 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.
