General Description
The IS31FL3237 is an LED driver with 36 constant current channels.
Each channel can be pulse width modulated (PWM) by 16 bits for smooth LED brightness control.
In addition, each channel has an 8-bit output current control register which allows fine tuning the current for rich RGB color mixing, e.g.
