GENERAL DESCRIPTION

This user guide describes the evaluation of the ADP5055 and
includes a detailed schematic and printed circuit board (PCB)
layouts.
The ADP5055-EVALZ features the ADP5055, which combines
three high performance buck regulators in a 43-terminal land
grid array (LGA) to meet the demanding performance and
board space requirements. The ADP5055-EVALZ connects to
input voltages up to 18 V directly, without any preregulators.
The ADP5055 includes a PMBus®-compatible serial interface
and the ADP5055-EVALZ can be used with an external USB
dongle and graphical user interface (GUI) software to evaluate
the power management functionalities and to read back system
status.
Full details on the device are provided in the ADP5055 data
sheet, available from Analog Devices, Inc. Consult this data
sheet in conjunction with this user guide when evaluating the
ADP5055.
