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  
„ Fixed High Frequency Operation 1MHz  
„ “Zero” Current Shutdown Mode  
„ Soft start and current limiting  
„ Short circuit protection  
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.  
„ Thermal shutdown protection  
The LED channels are configured into three indepen-  
dent 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.  
APPLICATIONS  
„ RGB LEDs  
„ LCD and keypad Backlighting  
„ Cellular Phones, PDAs  
„ Digital Cameras  
The device is available in a 16-pad TQFN package  
with a max height of 0.8mm.
