CAT3637  
6-Channel Programmable 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 6 LEDs between 30mA and 0mA each  
„ 1-wire EZDimTM interface with 2mA step  
„ Power efficiency up to 92%  
The CAT3637 is a high efficiency Quad-Mode fractional  
charge pump that can drive up to six LEDs program-  
mable 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 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 2.5V to 5.5V.  
„ Short circuit protection  
„ Thermal shutdown protection  
„ Tiny 3mm x 3mm, 16-pad TQFN package  
The EN/SET logic input functions as a chip enable and a  
digital programming interface for setting the current in the  
LED channels. The 1-wire pulse-programming interface  
supports 15 linear steps from zero current to 30mA full-  
brightness in 2mA steps.  
APPLICATIONS  
„ LCD Display Backlight  
„ Cellular Phones  
„ Digital Still Cameras  
„ Handheld Devices  
The device is available in a tiny 16-pad TQFN 3 x 3mm  
package with a maximum height of 0.8mm.  
Catalyst Semiconductor’s Quad-Mode 1.33x, charge pump  
switching architecture is patented.
