Exar XRP7618 8-Channel
Constant Current LED Driver

The Exar XRP7618 is an 8-Channel, high voltage, constant-current sink LED driver capable of driving up to 100mA current per channel. With outputs rated at 30V, the XRP7618 can control strings of multiple LEDs with better than ±1.5% channel to channel current matching. LED channel current is programmed via an external resistor on this Exar XRP7618 8-Channel Constant Current LED Driver within a 10mA to 100mA range. Dimming control is supported through a standard PWM scheme of up to 25kHz or through an analog signal. Exar's XRP7618 features Smart Talk™ technology, when combined with a boost converter, it maximizes the overall system efficiency by dynamically reporting the minimum LED voltage necessary to maintain current regulation mode.
