High Efficiency Ultra Small

Thinnest White LED Driver

The NCP5612 product is a dual output LED driver dedicated to the

LCD display backlighting.

The built−in DC/DC converter is based on a high efficient charge

pump structure with operating mode 1x and 1.5x. It provides a peak

87% efficiency together with a 0.2% LED to LED matching.
