CAT3614  
4-Channel 1-Wire LED Driver in  
3x3mm Package  
FEATURES  
DESCRIPTION  
„ Drives up to 4 LED channels  
„ 1-wire EZDimTM Programmable LED Current  
„ Accurate 1mA Dimming Level  
„ Power efficiency up to 91%  
The CAT3614 is a high efficiency 1x/1.5x fractional  
charge pump with programmable dimming current in  
four LED channels. To ensure uniform brightness in  
LCD backlight applications, each LED channel  
delivers an accurate regulated current.  
„ Fractional pump 1x/1.5x  
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.  
The EN/DIM logic input provides a 1-wire EZDimTM  
interface for dimming control of the LEDs. When  
enabled, a series of clock pulses reduces the LED  
brightness in 1mA steps on each negative going  
edge. Currents from 0mA to 31mA are supported.  
„ Low noise input ripple  
„ Fixed High Frequency Operation 1MHz  
„ “Zero” Current Shutdown Mode  
„ Soft start and current limiting  
„ Short circuit protection  
„ Thermal shutdown protection  
„ 12-lead TDFN 3mm x 3mm package  
APPLICATIONS  
„ LCD Display Backlight  
„ Cellular Phones  
„ Digital Still Cameras  
„ Handheld Devices  
The device is available in the tiny 12-lead thin DFN  
3mm x 3mm package with a max height of 0.8mm.
