CAT3643  
3-Channel Ultra High Efficiency Quad-Mode™  
LED Driver  
FEATURES  
DESCRIPTION  
„ 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%  
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  
capacitors.  
„ Low noise input ripple in all modes  
„ “Zero” current shutdown mode  
„ Soft start and current limiting  
Low noise input ripple is achieved by operating at a  
constant switching frequency which allows the use of  
small external ceramic capacitors. The multi-fractional  
charge pump supports a wide range of input voltages  
from 2.4V to 5.5V.  
„ Short circuit protection  
„ Thermal shutdown protection  
„ Tiny 12-lead XQFN, 12-lead TDFN and 16-lead  
The EN/DIM logic input functions as a chip enable and  
a digital dimming interface for current setting of all  
LEDs. Six different current ratios are available via the  
interface.  
TQFN packages  
APPLICATION  
„ LCD Display Backlight  
„ Cellular Phones  
The device is available in the tiny 12-lead XQFN 2.5 x  
2.5mm with max height of 0.4mm or in 16-lead TQFN  
or 12-lead TDFN 3mm x 3mm package with a max  
height of 0.8mm.  
„ Digital Still Cameras  
„ Handheld Devices  
The 1.33x charge pump architecture with two fly  
capacitors is patent pending.
