Mouser – High-performance 8-Channel constant-current sink LED driver (XRP7618IGBTR-F)

Now available from Mouser stock, 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.

Typical applications include LCD backlighting, desktop / notebook and TV displays, industrial / medical displays and signage backlighting.

LED channel current is programmed via an external resistor within a 10mA to 100mA range. Dimming control is supported through a standard PWM scheme of up to 25kHz or through an analog signal.  The 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, says the company.
