BD8118FM High efficiency Power LEDdriver for LCD Backlighting

The automotive grade BD8118FM is designed for medium sized LCD back lighting applications. It integrates four precisely matched current sources to drive four LED chains with up to 150mA each. LED luminance can be controlled by PWM (0.38%-100%) or VDAC. The output voltage of the integrated boost converter is regulated to minimize voltage drop of the current sources. It can be controlled by an enable switch and features a Soft Start mode to eliminate overshoot. The switching frequency is adjustable by synchronization or ext. RC.
