ADP5350CP-EVALZ User Guide
GENERAL DESCRIPTION
This user guide describes the hardware and software for the
evaluation of the
ADP5350CP-EVALZ
includes detailed schematics and printed circuit board (PCB)
layouts.
The
ADP5350
combines one high performance buck regulator
for single Li-ion/Li-ion polymer battery charging, a fuel gauge,
a highly programmable boost regulator for LED backlight
illumination, one ultralow quiescent current low dropout
(LDO) regulator, and two general-purpose LDO regulators.
The
ADP5350CP-EVALZ
external USB dongle connection and the GUI software allows
the user to evaluate the comprehensive functionalities provided
2
by the I
C interface.
The
ADP5350
operates over the −40°C to +125°C junction
temperature range and is available in a 32-lead, 5 mm × 5 mm
LFCSP package.
Full details on the device are provided in the
sheet, available from Analog Devices, Inc., which must be
consulted in conjunction with this evaluation board user guide.
