3-CHANNEL FUN LED DRIVER

December 2014

GENERAL DESCRIPTION

FEATURES

IS31FL3193 is a 3-channel fun LED driver which

features two-dimensional auto breathing mode. It has

One Shot Programming mode and PWM Control mode

for RGB lighting effects. The maximum output current

can be adjusted in 5 levels (5mA~42mA).



One group RGB, single color LED breathing

system-free pre-established pattern

3 independently controlled automatic and

semiautomatic breathing system-free

pre-established pattern

In PWM Control mode, the PWM duty cycle of each

output can be independently programmed and



I2C interface, automatic address increment

function

controlled in 256 steps to simplify color mixing. In One

Shot Programming mode, the timing characteristics for

output current - current rising, holding, falling and off

time, can be adjusted individually so that each output

can independently maintain a pre-established pattern

achieving mixing color breathing or a single color

breathing without requiring any additional interface

activity, thus saving valuable system resources.

3 independently controlled outputs of 256 PWM

steps



2.7V to 5.5V supply voltage

5 levels programmable output current

Over-temperature protection

Operating temperature T_A= −40°C ~ +85°C

DFN-10 (3mm × 3mm) package

IS31FL3193 is available in DFN-10 (3mm × 3mm). It

operates from 2.7V to 5.5V over the temperature range

of -40°C to +85°C.

APPLICATIONS



Mobile phones and other hand-held devices for

LED display

LED in home appliances
