ST2226A PWM-Controlled Constant Current Driver

The ST2226A is a LED driver incorporating shift registers, data latches, 16-channel constant current circuitry with current value set by an external resistor, 1024 gray level PWM (Pulse Width Modulation) functional unit and time division capability. Each channel can provide a maximum current of 60 m.
