CAT3626

6-Channel LED Driver with

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.

CASE 510AE

The LED channels are configured into three independent pairs, each

containing 2 matched channels. Each pair can be separately

programmed from zero to 32 mA, in 0.5 mA resolution steps, using

PIN CONNECTIONS

the I C 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.

The device is available in a 16−pad TQFN package with a max

height of 0.8 mm.
