EVALUATION KIT CONTENTS
ADP1055-EVALZ evaluation board
ADP1055DC1-EVALZ daughter card
ADDITIONAL EQUIPMENT NEEDED
The USB-I
2
C connector, ADP-I2C-USB-Z, with Driver CD
(must order separately from Analog Devices, Inc.)
GENERAL DESCRIPTION
This evaluation board, together with a daughter card, allows
you to evaluate the ADP1055 as a power supply application.
With the USB to I
2
C connector, and the graphical user interface
(GUI), the ADP1055 on the evaluation board can be interfaced
with a PC via a USB port.
The evaluation board is set up to act as an isolated PSU with
a rated load of 12 V, 20 A from a 38 V dc to 60 V dc source.
Connectors on the evaluation board provide synchronization,
as well as share bus and PMBus™ interfaces, allowing direct
parallel evaluation when multiple evaluation boards are
connected in parallel to a common bus.
Multiple test points allow easy access to all critical points/pins.
