1-CHANNEL FUN LED DRIVER

Preliminary Information

November 2015

GENERAL DESCRIPTION

IS31FL3190 is a 1-channel fun LED driver which has

One Shot Programming mode and PWM Control mode

for LED lighting effects. The maximum output current

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

In PWM Control mode, the PWM duty cycle of each

output can be independently programmed and

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.

IS31FL3190 is available in UTQFN-9 (1.5mm ×

1.5mm). It operates from 2.7V to 5.5V over the

temperature range of -40°C to +85°C.

FEATURES

 Independently controlled automatic and

semiautomatic breathing system-free

pre-established pattern

 I2C interface, automatic address increment

function

 Independently controlled output of 256 PWM

steps

 2.7V to 5.5V supply voltage

 5 levels programmable output current

 Provide auto breathing current control with 640

levels (5×128)

 Over-temperature protection

 Operating temperature T

= −40°C ~ +85°C

 UTQFN-9 (1.5mm × 1.5mm) package

APPLICATIONS

 Mobile phones and other hand-held devices for

LED display

 LED in home appliances
