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.

The chip can be turned off by pulling the SDB pin low or

by using the software shutdown feature to reduce

power consumption.

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.
