IS31FL3235A  
28 CHANNELS LED DRIVER  
February 2017  
GENERAL DESCRIPTION  
FEATURES  
IS31FL3235A is comprised of 28 constant current  
channels each with independent PWM control,  
designed for driving LEDs, PWM frequency can be  
3kHz or 22kHz. 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  
PWM frequency selectable  
- 3kHz (default)  
- 22kHz  
The chip can be turned off by pulling the SDB pin low or  
by using the software shutdown feature to reduce  
power consumption.  
-40°C to +85°C temperature range  
ESD HBM 8kV  
QFN-36 (4mm × 4mm) package  
IS31FL3235A is available in QFN-36 (4mm × 4mm)  
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 1: The maximum global output current is set up to 23mA when REXT = 3.3kΩ. The maximum global output current can be set by external  
resistor, REXT. Please refer to the detail information in Page 10.  
Note 2: The IC should be placed far away from the mobile antenna in order to prevent the EMI.
