The IS31FL3733 is a general-purpose 12×16 LEDs matrix driver with 1/12 cycle rate. The device can be programmed via an I2C compatible interface. Each LED can be dimmed individually with 8-bit PWM data which allows 256 steps of linear dimming.

36 constant current LED channels each with independent PWM control for accurate color mixing. 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 IS32FL3237 is driven by the IS32LT3183A configured as a LIN-to-I2C translator and a 12V-to-5V DC/DC converter.

The IS32LT3175 is a single channel linear programmable current regulator capable of up to 150mA. It integrates a debounce and latch circuit on the channel enable pin (EN) to facilitate the use of a low-cost momentary contact switch.

This video is of a demo application for an appliance control panel using the matrix LED driver IS31FL3733 and the IS31SE5118A microcontroller based capacitance touch sensor.
