CAT3637 Datasheet (Catalyst Semiconductor) - 6-Channel Programmable High Efficiency Quad-Mode LED Driver

CAT3637, 6-Channel Programmable High Efficiency Quad-Mode LED Driver

The CAT3637 is a high efficiency Quad-Mode fractional charge pump that can drive up to six LEDs programmable by a 1-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 capacito
