Overview

CAT3614 4-Channel 1-Wire LED Driver in 3 x 3 mm Package Description 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.
Low noise and input ripple is achieved by operating at a constant switching frequency of 1 MHz which allows the use of small external ceramic capacitors.
The 1x/1.
5x fractional charge pump supports a wide range of input voltages from 3 V to 5.
5 V with efficiency up to 91%, and is ideal for Li−Ion battery powered devices.
The EN/DIM logic input provides a 1−wire EZDimt interface for dimming c...
