CAT3647 Datasheet (Catalyst Semiconductor) - 3-Channel Ultra High Efficiency Quad-Mode LED Driver

CAT3647, 3-Channel Ultra High Efficiency Quad-Mode LED Driver

The CAT3647 is a high efficiency quad-mode fractional charge pump that can drive up to three 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 capa
