The IS31FL3236A is a constant current LED driver with 36 channels, each featuring independent 256-step PWM control. It operates from a 2.7V to 5.5V supply and allows for a maximum output current of 38mA per channel, set by an external resistor. The device supports I2C communication with four selectable addresses and features a selectable PWM frequency of 3kHz or 22kHz to minimize audible noise.
