Functional Description
The ZL8101_30AEV2Z 30A Demo Board provides all circuitry
required to demonstrate the features of the ZL8101. The ZL8101
30A has a functionally optimized ZL8101 circuit layout that
allows efficient operation up to the maximum output current.
Power and load connections are provided through plug-in
sockets.
A majority of the features of the ZL8101 such as soft-start delay
and ramp times, supply sequencing, voltage tracking, and
voltage margining are available on this board. For voltage
tracking and sequencing evaluation, the board can be connected
to any other Zilker Labs evaluation boards that supports the
Digital DC (DDC) bus.
Figure1 shows a simplified schematic of the ZL8101_30AEV2Z
30A Demo Board. All power to the board (VIN and I
be removed before changing the jumpers.
The hardware enable function is controlled by a toggle switch on
the ZL8101_30AEV2Z 30A board. The power-good (PG) LED
indicates the state of PG when external power is applied to the
ZL8101_30AEV2Z 30A board. The right angle headers at
opposite ends of the board are for connecting a USB to SMBus
adapter board or for easy chaining of multiple evaluation boards.
Figure 2 shows the ZL8101_30AEV2Z 30A Demo Board
complete circuit. The circuit consists of the ZL8101 IC with its
minimal component count to realize a 30A buck converter. The
board layout has been optimized for thermal performance.
Figure 3 is the board interface circuitry. Figures 5 through 10
show the PCB layout for the board, including the board
fabrication notes.
The bill of materials (BOM) and configuration file are also
included for reference.
Operation
PMBus Operation
The ZL8101 utilizes the PMBus protocol. The PMBus functionality
can be controlled via USB from a PC running the PowerNavigator
evaluation software in a Windows XP, Windows 2000/NT, or
Windows 7 operating system.
Install the evaluation software using the CD included in the
ZL8101_30AEV2Z 30A Demo Board kit.
For board operation, connect the included USB-to-SMBus adapter
board to J2 of the ZL8101_30AEV2Z 30A Demo board. Connect
the desired load and an appropriate power supply to the input
and connect the included USB cable to the PC running the
PowerNavigator evaluation software. Place the ENABLE switch in
“DISABLE” and turn on the power.
The evaluation software allows modification of all ZL8101
PMBus parameters. The ZL8101 device on the board has been
pre-configured as described in the Target Specifications on the
front page, but the user may modify the operating parameters
through the PowerNavigator software or by loading a predefined
scenario from a configuration file.
Use the mouse-over pop-ups for PowerNavigator help. Refer to

The ENABLE switch can then be moved to “ENABLE” and the
ZL8101_30AEV2Z 30A Demo board can be tested. Alternately,
the PMBus ON-OFF CONFIG and OPERATION commands may be
used.
