CAT3614

4-Channel 1-Wire LED Driver in

3x3mm Package

FEATURES

DESCRIPTION

Drives up to 4 LED channels

1-wire EZDim^TMProgrammable 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 EZDim^TM

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.
