CAT3636 Datasheet (ON Semiconductor)

CAT3636, LED Driver

The CAT3636 is a high efficiency fractional charge pump that can drive up to six LEDs programmable by a one wire digital interface.

The inclusion of a 1.33x fractional charge pump mode increases device efficiency by up to 10% over traditional 1.5x charge pumps with no added external capacitors.
