GENERAL DESCRIPTION
The XRP7620EVB Evaluation Board is designed
to demonstrate and evaluate the performance
of the XRP7620 device, a multi purpose 4-
channel independently adjustable current sink
driver.
Optimized for LED backlighting and
RGBW/RGBA color mixing applications, the
XRP7620 supports an industry standard 2-line
I 2 C serial interface providing full independent
control of each channel up to a current of
31.5mA in steps of 500μA.
The XRP7620 operates from 2.7V to 5.5V input
with 100mV dropout voltage and allows a wide
range of forward voltage LEDs.
The evaluation board is a completely
assembled and tested surface mount board
which provides easy probe access points so
that the user can quickly connect LEDs and
measure electrical characteristics. The
Evaluation Board schematic diagram is shown
in Figure 1.
