GENERAL DESCRIPTION
This user guide describes the hardware for the evaluation of
the ADP5023/ADP5024/ADP5034/ADP5037 and includes
detailed schematics and printed circuit board (PCB) layouts.
The ADP5023/ADP5024/ADP5034/ADP5037 are available in a
24-lead, 4 mm × 4 mm LFCSP package. The ADP5023/ADP5024
are 3-channel devices that share a common PCB evaluation
board. The ADP5034/ADP5037 are 4-channel devices that share
a common PCB evaluation board. The ADP5023, ADP5024,
ADP5034, and ADP5037 operate in the same manner. Note that
this user guide covers all of these boards, but refers to the
ADP5034 for simplicity.
The ADP5034 LFCSP evaluation board, ADP5034-1-EVA L Z ,
has two step-down regulators with two LDO regulators that
enable evaluation of the ADP5034. The evaluation board is
available in an adjustable voltage option.
For full details on the ADP5023, ADP5024, ADP5034, and
ADP5037, consult the appropriate product data sheet available
from Analog Devices, Inc., in conjunction with this evaluation
board user guide.
