CAT3626  
6-Channel LED Driver with I2C Interface  
FEATURES  
PRODUCT DESCRIPTION  
„ Drives 6 LED channels  
The CAT3626 is a high efficiency 1x/1.5x fractional  
charge pump with programmable dimming current in  
six LED channels. To ensure uniform brightness in  
LCD backlight applications, each LED channel  
delivers an accurate regulated current.  
„ Independent current on 3 pairs of LEDs  
„ I2C serial interface programming  
„ Adjustable current to 32mA in 0.5mA step  
„ Power efficiency up to 91%  
„ Fractional pump 1x/1.5x  
„ Low noise input ripple  
Low noise and input ripple is achieved by operating  
at a constant switching frequency of 1MHz which  
allows the use of small external ceramic capacitors.  
The 1x/1.5x fractional charge pump supports a wide  
range of input voltages from 3V to 5.5V with  
efficiency up to 91%, and is ideal for Li-Ion battery  
powered devices.  
„ Fixed High Frequency Operation 1MHz  
„ “Zero” Current Shutdown Mode  
„ Soft start and current limiting  
„ Short circuit protection  
„ Thermal shutdown protection  
APPLICATION  
The LED channels are configured into three  
independent pairs, each containing 2 matched  
channels. Each pair can be separately programmed  
from zero to 32mA, in 0.5mA resolution steps, using  
the I2C serial interface. Any individual channel can  
be disabled while others remain active. When the  
enable input (EN) is low, the device is in shutdown  
mode drawing zero current.  
„ RGB LEDs  
„ LCD and keypad Backlighting  
„ Cellular Phones, PDAs  
„ Digital Cameras
