GENERAL DESCRIPTION
The XRP7620 is a multi purpose 4-channel
independently adjustable current sink driver.
Optimized for LED backlighting and
RGBW/RGBA color mixing applications, the
XRP7620 can also be used as a generic
software programmable current sink I/O
expander.
2
serial interface, the XRP7620 provides full
independent control of each channel and can
be programmed up to a current of 31.5mA in
steps of 0.5mA. Uniform display brightness is
ensured through better than 3% channel to
channel current matching.
Five internal registers are provided to set
operational configuration and individual
channel current programmation. A specific
shutdown mode allows the device to retain the
previously loaded configuration – operational
and current programming – in order to be
reused upon the next enabling.
The XRP7620 is designed to operate from a
single cell lithium-ion battery or fixed 3.3V or
5.0V power rails and is available in a RoHS
compliant, “green”/ halogen free space saving
8-pin 2mmx3mm DFN package.
