Description
Features
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.
• 30A Single-phase and 60A Dual-phase Rails
The ZL6100EVAL2Z platform is a 6-layer board with two
power rails. One rail is a single phase, 30A power rail.
The other rail is a dual phase, 60A power rail
demonstrating the current sharing capability of the
ZL6100.

ZL6100EVAL2Z
Functional Description
The ZL6100EVAL2Z provides all circuitry required to
demonstrate the features of the ZL6100. The
ZL6100EVAL2Z 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.
All features of the ZL6100 such as current sharing, softstart delay and ramp times, supply sequencing, voltage
tracking, and voltage margining are available on this
evaluation board. For voltage tracking, the board is set
up for the single phase rail (VOUT2) to track the dual
phase rail (VOUT1). Contact the Zilker Labs sales office
for configuring the board for other tracking combinations.
Figure 1 shows a functional block diagram of the
ZL6100EVAL2Z 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.
The hardware enable function is controlled by a toggle
switch on the ZL6100EVAL2Z board. The power good
(PG) LEDs indicate the correct state of PG when external
power is applied to the ZL6100EVAL2Z board. (Note: If a
USB board is connected to the ZL6100EVAL2Z and no
power is applied to the board, the PG LEDs will turn on
even though the power rails are not enabled.) 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.
Figures 2 and 3 show the two phases of the 60A circuit.
Figure 4 shows the single phase operational circuit. The
circuit consists of the ZL6100 IC with its minimal
component count to realize a 30A buck converter. The
board layout has been optimized for thermal
performance.
Figure 5 is the Interface and Figure 9 SMBus address
selection circuitry.
been pre-configured as described in this document, but
the user may modify the operating parameters through
the eval software or by loading a predefined scenario
from a configuration file.
Use the mouse-over pop-ups for PowerNavigator help.
Refer to Zilker Labs application note AN2033 “PMBus™
Command Set DDC Products”, Intersil Corporation,
2009 for PMBus details.
The ENABLE switch can then be moved to “ENABLE” and
the ZL6100EVAL2Z board can be tested. Alternately, the
PMBus ON-OFF CONFIG and OPERATION commands may
be used.

Unless expressly designated as a high reliability product or a product for harsh environments in a Renesas Electronics data sheet or other Renesas Electronics document, Renesas Electronics products are
not intended or authorized for use in products or systems that may pose a direct threat to human life or bodily injury (artificial life support devices or systems; surgical implantations; etc.), or may cause
serious property damage (space system; undersea repeaters; nuclear power control systems; aircraft control systems; key plant systems; military equipment; etc.). Renesas Electronics disclaims any and all
liability for any damages or losses incurred by you or any third parties arising from the use of any Renesas Electronics product that is inconsistent with any Renesas Electronics data sheet, user’s manual or
other Renesas Electronics document.
6.
When using Renesas Electronics products, refer to the latest product information (data sheets, user’s manuals, application notes, “General Notes for Handling and Using Semiconductor Devices” in the
reliability handbook, etc.), and ensure that usage conditions are within the ranges specified by Renesas Electronics with respect to maximum ratings, operating power supply voltage range, heat dissipation
characteristics, installation, etc. Renesas Electronics disclaims any and all liability for any malfunctions, failure or accident arising out of the use of Renesas Electronics products outside of such specified
ranges.
7.
Although Renesas Electronics endeavors to improve the quality and reliability of Renesas Electronics products, semiconductor products have specific characteristics, such as the occurrence of failure at a
certain rate and malfunctions under certain use conditions. Unless designated as a high reliability product or a product for harsh environments in a Renesas Electronics data sheet or other Renesas
Electronics document, Renesas Electronics products are not subject to radiation resistance design. You are responsible for implementing safety measures to guard against the possibility of bodily injury, injury
or damage caused by fire, and/or danger to the public in the event of a failure or malfunction of Renesas Electronics products, such as safety design for hardware and software, including but not limited to
redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the evaluation of microcomputer software alone is very difficult
and impractical, you are responsible for evaluating the safety of the final products or systems manufactured by you.
8.
Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental compatibility of each Renesas Electronics product. You are responsible for carefully and
sufficiently investigating applicable laws and regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS Directive, and using Renesas Electronics
products in compliance with all these applicable laws and regulations. Renesas Electronics disclaims any and all liability for damages or losses occurring as a result of your noncompliance with applicable
laws and regulations.
9.
Renesas Electronics products and technologies shall not be used for or incorporated into any products or systems whose manufacture, use, or sale is prohibited under any applicable domestic or foreign laws
or regulations. You shall comply with any applicable export control laws and regulations promulgated and administered by the governments of any countries asserting jurisdiction over the parties or
transactions.
10. It is the responsibility of the buyer or distributor of Renesas Electronics products, or any other party who distributes, disposes of, or otherwise sells or transfers the product to a third party, to notify such third
party in advance of the contents and conditions set forth in this document.
11. This document shall not be reprinted, reproduced or duplicated in any form, in whole or in part, without prior written consent of Renesas Electronics.
12. Please contact a Renesas Electronics sales office if you have any questions regarding the information contained in this document or Renesas Electronics products.
