IS31FL3235A - 28 CHANNELS LED DRIVER

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 an.

IS31FL3235A Features

* 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
