Additional preview pages of the IS31FL3749 datasheet.

IS31FL3749 is a matrix LED driver with 24 high voltage (16V) constant current channels.

It supports from one to four power scan to become a 24×n (n=1~4) matrix LED driver.

Each LED can be pulse width modulated (PWM) with maximum 16-bit precision for smooth LED brightness control.

Support 24 constant current channels, 60mA/ch.
Tolerate up to 20V, nominal operation voltage between 4.3V to 16V, multiple LED’s can be connected in series.
Built-in LDO to generate 4.8V supply for internal logic (option to float it and use external power).
Interface - VSB (video serial bus, 33MHz) - SPI (33MHz).
Reset register reset all the registers to default.
Support 8-bit, 16-bit, 8+4-bit dithering and 8+8bit dithering PWM mode.
