GENERAL 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 Talk TM technology,
when combined with a boost converter, the
XRP7618 maximizes the overall system
efficiency by dynamically reporting the
minimum LED voltage necessary to maintain
current regulation mode. Multiple channels can
be combined to increase current driving
capability per channel and multiple XRP7618s
can be placed in parallel to drive over 8 strings
of LEDs.
An under voltage lock out, open LED and over
temperature protections insure safe operations
under abnormal operating conditions.
