Overview

CAT3626 LED Driver, Charge Pump, 6-Channel, I2Ct Interface Description 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.
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 LED channels are configured into three independent pairs, each c...
