IS32FL3265A 18-CHANNEL LED DRIVER

The IS32FL3265A is an LED driver with 18 high voltage (40V) constant current channels. Each channel can be pulse width modulated (PWM) by 8 bits for smooth LED brightness control. In addition, each channel has an 8-bit output current control register which allows fine tuning of the channel current for rich RGB color mixing, e.g., a pure white color LED appli.
