1 Background
The TPS65400 is an integrated power management unit (PMU) optimized for applications that require small form
factor and high-power conversion efficiency, enabling small space-constrained equipment with high-ambient
operating temperature without cooling. The TPS65400 provides high-power efficiency at a system level by
enabling a single-stage conversion from an intermediate distribution bus with an optimized combination of
regulators.
The TPS65400 consists of four high-current buck-switching regulators (SW1, SW2, SW3, and SW4) with
integrated FETs. The switching power supplies are intended for powering high-current digital circuits such as
the processor, FPGA, ASIC, memory, and digital I/Os. SW1 and SW2 support 4 A each, and SW3 and SW4
support 2 A each. Each regulator’s switching frequency is independently adjustable up to 2.2 MHz.
Current limit programmability on each switcher enables optimization of inductor ratings for a particular
application configuration not requiring the maximum current capability. The TPS65400 can be powered from
a single-input voltage rail between 4.5 and 18 V, making it suitable for applications running off a 5- or 12-V
intermediate power distribution bus. Sequencing requirements can be met using the individual enable pins or by
programming the sequence through the I2C bus into the onboard EEPROM. Output voltages can be set through
external resistor networks and VREF can be programmed from 0.6 to 1.87 V in 10-mV steps. All control and
status info can be accessed through a PMBus-compatible I2C bus.
The TPS65400 provides a high level of flexibility for monitoring and control through the I2C bus while providing
the option of programmability through the use of external components and voltage levels for systems not using
I2C. As there are many possible options to set the converters, Table 1-1 presents the performance specification
summary for the EVM.
The evaluation module is designed to provide access to the features of the TPS65400. Some modifications can
be made to this module to test performance at different input and output voltages for bucks. Please contact the
TI Field Applications group for advice on these matters.
As there are many possible options to set the converters, Table 1-1 presents the performance specification
summary for the EVM.

4.2 Hardware Requirement
This EVM requires an external power supply capable of providing 4.5 V to 18 V at 6 A.
The EVM kit includes USB2ANY interface box which, when installed on a PC and connected to the EVM, permits
communication with the EVM via a GUI interface. The minimum PC requirements are:
• Microsoft® Windows® 2000, Windows XP, or Windows 7 operating system
• USB port
• Minimum of 30MB of free hard disk space (100MB recommended)
• Minimum of 256MB of RAM
4.3 Hardware Setup
After connecting the power supply to J6 and turning on the power supply, the EVM regulates the output voltages
to the value listed in Table 1-1. Additional input capacitance may be required in order to mitigate the inductive
voltage droop that may occur during a load transient event.
In order to change the output voltage by sending the digital control signal via a PC running the TPS65400
controller software and USB2ANY interface box, perform the following steps:
1. Connect the USB port of USB2ANY to the PC using the USB cable and the other end to J13 of the
TPS65400 using the supplied 30-pin ribbon cable (Figure 4-2). The connectors on the ribbon cable are
keyed to prevent incorrect installation.
2. Connect the power supply on J6 and turn on the power supply.
3. Run the software as explained in Section 4.4.

4.4 Software Install
If installing from the TI Web site, go to the URL, www.ti.com
Note
This installation page is best viewed with the Microsoft® Internet Explorer® browser and may not work
correctly with other browsers.
Click on the install button; the PC should give a security warning asking if you want to install this application.
Select Install to proceed. If a pre-release or Beta version is currently installed on the PC, uninstall this version of
the software before installing the final version.
The software attempts to install the Microsoft® .NET Framework 2.0 (if it is not already installed). This framework
is required for the software to run.
To run the software after installation, go to
Start → All programs → Texas Instruments → PI-Commander-0.8.4-672M → PI-Commander-PMU.
At start-up, the software first checks the firmware version of the USB2ANY adapter box. If an incorrect firmware
version is installed, the software automatically searches on the Internet (if connected) for updates. If a new
update is available, the software notifies the user of the update, and downloads and installs the software. Note
that after the firmware is updated, the USB cable between the adapter and PC must be disconnected and then
reconnected, as instructed during the install process. The host PC software also automatically searches on the
Internet (if connected) for updates. If a new update is available, the software notifies the user of the update and
downloads and installs it. During future use of the software, it may prompt you to install a new version if one
becomes available on the Web.
Note
VeriSign® Code Signing is used to prevent any malicious code from changing this application. If at any
time in the future the binaries are modified, the code will no longer attempt to run.

STANDARD TERMS FOR EVALUATION MODULES
1. Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or
documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance
with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
WARNING
Evaluation Kits are intended solely for use by technically qualified,
professional electronics experts who are familiar with the dangers
and application risks associated with handling electrical mechanical
components, systems, and subsystems.
User shall operate the Evaluation Kit within TI’s recommended
guidelines and any applicable legal or environmental requirements
as well as reasonable and customary safeguards. Failure to set up
and/or operate the Evaluation Kit within TI’s recommended
guidelines may result in personal injury or death or property
damage. Proper set up entails following TI’s instructions for
electrical ratings of interface circuits such as input, output and
electrical loads.
NOTE:
EXPOSURE TO ELECTROSTATIC DISCHARGE (ESD) MAY CAUSE DEGREDATION OR FAILURE OF THE EVALUATION
KIT; TI RECOMMENDS STORAGE OF THE EVALUATION KIT IN A PROTECTIVE ESD BAG.

otherwise marketed unless all required FCC equipment authorizations are first obtained. Operation is subject to the condition
that this product not cause harmful interference to licensed radio stations and that this product accept harmful interference.
Unless the assembled kit is designed to operate under part 15, part 18 or part 95 of this chapter, the operator of the kit must
operate under the authority of an FCC license holder or must secure an experimental authorization under part 5 of this chapter.
3.1.2 For EVMs annotated as FCC – FEDERAL COMMUNICATIONS COMMISSION Part 15 Compliant:
CAUTION
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to
operate the equipment.
FCC Interference Statement for Class A EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
FCC Interference Statement for Class B EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
