IS31FL3236  
36 CHANNELS LED DRIVER  
July 2012  
GENERAL DESCRIPTION  
FEATURES  
IS31FL3236 is comprised of 36 constant current  
channels each with independent PWM control,  
designed for driving LEDs. The output current of each  
channel can be set at up to 38mA (Max.) by an external  
resistor and independently scaled by a factor of 1, 1/2,  
1/3 and 1/4. The average LED current of each channel  
can be changed in 256 steps by changing the PWM  
duty cycle through an I2C interface.  
2.7V to 5.5V supply  
I2C interface, automatic address increment  
function  
Internal reset register  
Modulate LED brightness with 256 steps PWM  
Each channel can be controlled independently  
Each channel can be scaled independently by 1,  
1/2, 1/3 and 1/4  
-40°C to +85°C temperature range  
The chip can be turned off by pulling the SDB pin low or  
by using the software shutdown feature to reduce  
power consumption.  
QFN-44 (5mm × 5mm) and TQFP-48 package  
IS31FL3236 is available in QFN-44 (5mm × 5mm) and  
TQFP-48 package. 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  
TYPICAL APPLICATION CIRCUIT  
Figure 1 Typical Application Circuit  
Note: The maximum global output current is set up to 23mA when REXT = 3.3k. The maximum global output current can be set by external  
resistor, REXT. Please refer to the detail information in Page 11.  
Note: The IC should be placed far away from the mobile antenna in order to prevent the EMI.
