CAT3643 Datasheet - Catalyst Semiconductor

CAT3643 3-Channel Ultra High Efficiency Quad-Mode TM LED Driver

The CAT3643 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.

CAT3643 Features

* High efficiency 1.33x charge pump

* Quad-mode charge pump: 1x, 1.33x, 1.5x, 2x

* Drives up to 3 LEDs at 32mA each

* 1-wire EZDim™ LED current programming

* Power efficiency up to 92%

* Low noise input ripple in all modes

* “Zero” current shut
