ZL6100EVAL1Z Evaluation Board
The ZL6100 is an integrated mixed-signal power
conversion and management IC that combines an
efficient step-down DC/DC converter with key power and
thermal management functions in a single package. The
ZL6100 incorporates current sharing and adaptive
efficiency-optimization algorithms to provide a flexible,
efficient power IC building block.
The ZL6100EVAL1Z platform is a 4-layer board
demonstrating a 15A synchronous buck converter.
Sequencing, tracking, margining, plus other features can
be evaluated using this board.
A USB to SMBus adapter board can be used to connect
the evaluation board to a PC. The PMBus command set is
accessed by using the Zilker Labs PowerNavigator™
evaluation software from a PC running Microsoft
Windows.
Key Features
• 15A Synchronous Buck Converter
• Optimized for Small Circuit Footprint and Dynamic
Response
• Configurable through SMBus
• Onboard Enable Switch
• Power-Good Indicator

DESCRIPTION
ZL6100EVAL1Z ZL6100 Evaluation Kit (EVB, USB Adapter,
Cable, Software)
Target Specifications
• VIN = 12V
• VOUT = 1.2V/15A (20A max)
• fsw = 400kHz
• Efficiency: 86% at 10A
• Output Ripple: ±1%
• Dynamic Response: ±3%
(50% to 100% to 50% load step, di/dt = 2.5A/µs)
• Board Temperature: +25°C
Functional Description
The ZL6100EVAL1Z provides all circuitry required to
demonstrate the features of the ZL6100. The
ZL6100EVAL1Z has a functionally-optimized ZL6100
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 ZL6100 such as
soft-start delay and ramp times, supply sequencing,
voltage tracking, and voltage margining are available on
this evaluation board. For voltage tracking and
sequencing evaluation, the board can be connected to
any other Zilker Labs evaluation board that supports the
Digital DC (DDC) bus.
Figure 1 shows a functional block diagram of the
ZL6100EVAL1Z board. The SMBus address is selectable
through a jumper on the top side of the board. All power
to the board (VIN and I2C bus) must be removed before
changing the jumpers.

Application Note 1493
The hardware enable function is controlled by a toggle
switch on the ZL6100EVAL1Z board. The power-good
(PG) LEDs indicate the correct state of PG when external
power is applied to the ZL6100EVAL1Z board. The right
angle headers at opposite ends of the board are for
connecting a USB to SMBus adapter board or for daisy
chaining of multiple evaluation boards.
Figure 2 shows the operational circuit. The circuit
consists of the ZL6100 IC with its minimal component
count to realize a 15A buck converter. The board layout
has been optimized for thermal performance. Figure 3 is
the board interface circuitry and Figures 4 through 8
demonstrate the PCB Board Layout, which includes the
board fabrication notes.
4. Connect supplied USB cable from computer to USB
to SMBus adapter board (Optional: provides power
for onboard LED’s so that LED power does not
detract from efficiency measurement)
5. Connect power supply to VIN+/VIN- (supply turned
off)
6. Turn power supply on
7. Set ENABLE switch to “ENABLE”
8. Monitor ZL6100EVAL1Z board operation using an
oscilloscope
USB (PMBus) Operation
1. Set ENABLE switch to “DISABLE”
The Bill of Materials (BOM) and configuration file are also
included for reference beginning on page 10.
2. Apply load to VOUT+/VOUT3. Connect power supply to VIN+/VIN- (supply turned
off)
Operation
4. Turn power supply on
5. Insert the Zilker Labs Eval Kit CD
PMBus Operation
The ZL6100 utilizes the PMBus protocol. The PMBus
functionality can be controlled via USB from a PC running
the PowerNavigator evaluation software in a Windows XP
or Windows 2000/NT operating system.
Install the evaluation software using the CD included in
the ZL6100EVAL1Z kit.
For board operation, connect the included USB-to-SMBus
adapter board to J10 of the ZL6100EVAL1Z 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 ZL6100
PMBus parameters. The ZL6100 device on the board has
been pre-configured as described in this document, but
the user may modify the operating parameters through
the evaluation software or by loading a predefined
scenario from a configuration file.
6. Connect USB to SMBus adapter board to J10 of
ZL6100EVAL1Z
7. Connect supplied USB cable from computer to USB
to SMBus adapter board.
- Upon first-time connection, the Found New
Hardware Wizard will appear.
- Windows XP users: Select ‘No’ at prompt to search
the Internet for drivers.
- Follow the steps on the screen to install the drivers
from the CD.
8. Install the PowerNavigator evaluation software by
running setup.exe from the
PowerNavigator_installer folder on the CD.
9. Set ENABLE switch on EVB to “ENABLE”
10.Monitor and configure the ZL6100EVAL1Z board
using PMBus commands in the evaluation software
11.Test the ZL6100EVAL1Z operation using an
oscilloscope and the evaluation software.
Use the mouse-over pop-ups for PowerNavigator help.
Refer to Zilker Labs application note AN2033 for PMBus
details.
The ENABLE switch can then be moved to “ENABLE” and
the ZL6100EVAL1Z board can be tested. Alternately, the
PMBus ON-OFF CONFIG and OPERATION commands may
be used.
Quick Start Guide
Stand Alone Operation
1. Set ENABLE switch to “DISABLE”
2. Apply load to VOUT+/VOUT3. Connect the USB to SMBus adapter board to J10 of
ZL6100EVAL1Z (Optional: provides power for
onboard LED’s so that LED power does not detract
from efficiency measurement)
