4-Channel White LED Driver with Integrated FET for up to 40 LEDs - BD65D00MUV

This IC is white LED driver IC with PWM step-up DC/DC converter that can boost max 41V and current driver that can drive max 100mA. The wide and precision brightness can be controlled by external PWM pulse. This IC 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.
It can respond to the application according to the application to be abele to switch to external/internal NchFET boosting.

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