ERAL DESCRIPTION The 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 within a 10mA to 100mA range. Dimming control is supported through a standard PWM scheme up to 25kHz or through an analog signal. Featuring Exar’s Smart TalkTM technology, when combined with a boost converter, the XRP7618 maximizes the overall system efficiency by dynamically reporting the
