Introduction
This User's Guide contains background information for the TPS54678 as well as support documentation
for the TPS54678EVM-155 evaluation module (EVM) (PWR155). Also included are the performance
specifications, the schematic, and the bill of materials for the EVM.
1.1
Background
The TPS54678 dc/dc converter is designed to provide up to a 6-A output from an input voltage source of
2.95 V to 6 V. Rated input voltage and output current range for the EVM are given in Table 1. This EVM
demonstrates the small printed-circuit board areas that are achieved when designing with the TPS54678
regulator. The switching frequency is externally set at a nominal 500 kHz. The high-side and low-side
MOSFETs are incorporated inside the TPS54678 package along with the gate-drive circuitry. The low
drain-to-source on resistance of the MOSFETs allow the TPS54678 to achieve high efficiencies and helps
keep the junction temperature low at high output currents. The compensation components are external to
the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the
TPS54678 provides adjustable slow start and undervoltage lockout inputs. The absolute maximum input
voltage is 7 V for the EVM.

Modifications
These evaluation modules are designed to provide access to the features of the TPS54678. This module
can be modified.
1.3.1
Output Voltage Set Point
The voltage dividers, R9 and R10, are used to set the output voltage. Change the output voltage of the
EVM by changing the value of resistor R9. Changing the value of R9 changes the output voltage above
0.6 V. The value of R9 for a specific output voltage is calculated using Equation 1. Use 10.0 kΩ for R10.
V
R9 = R10 ×( OUT - 1)
0.6 V
(1)
Table 3 lists the R9 and R10 values for some common output voltages. Note that VIN must be in a range
so that the minimum on-time is greater than 80 ns, and the maximum duty cycle is less than 92%. The
values given in Table 3 show standard values and the closest E96 match.

Test Setup and Results
This section describes how to properly connect, set up, and use the EVM. The section also includes test
results typical for the EVM and covers efficiency, output voltage regulation, load transients, loop response,
output ripple, input ripple, and start-up.
2.1
Input/Output Connections
The EVM is provided with input/output connectors and test points as shown in Table 4 and Figure 1. A
power supply capable of supplying 3 A must be connected to J1 through a pair of 20 AWG wires. The load
must be connected to J2 through a pair of 20 AWG wires. The maximum load current capability must be at
least 6 A to use the full capability of this EVM. Wire lengths must be minimized to reduce losses in the
wires. Test-point, TP1, provides a place to monitor the VIN input voltages with TP2 providing a convenient
ground reference. TP8 is used to monitor the output voltage with TP9 as the ground reference.

Powering Up
Figure 11 and Figure 12 show the start-up waveforms for the EVM. In Figure 11, the output voltage ramps
up as soon as the input voltage reaches the UVLO threshold as set by the R1 and R2 resistor divider
network. In Figure 12, the input voltage is initially applied and the output is inhibited by using a jumper at
JP1 to tie EN to GND. When the jumper is removed, EN is released. When the EN voltage reaches the
enable-threshold voltage, the start-up sequence begins and the output voltage ramps up to the externally
set value of 1.2 V.

ramps down as soon as the input voltage falls below the UVLO stop threshold as set by the R1 and R2
resistor divider network. At the point of shutdown, the input voltage rises slightly due to the resistive drop
in the input feed impedance. In Figure 15, the output is inhibited by using a jumper at JP1 to tie EN to
GND.

2.11 Hiccup Mode Current Limit
The TPS54678 has hiccup mode current limit. When the peak switch current exceeds the current limit
threshold, the device shuts down and restarts. Hiccup mode current limit operation is shown in Figure 16
and Figure 17. Figure 16 shows the activation of hiccup mode current limit. When the peak current limit is
exceeded, the output voltage is disabled. Figure 17 shows the operation of the TPS54678 with the output
shorted to ground. The device will continuously reset until the fault condition is removed.

Board Layout
This section provides a description of the EVM, board layout, and layer illustrations.
3.1
Layout
The following figures show the board layout for the EVM. The topside layer of the EVM is laid out in a
manner typical of a user application. The top and bottom layers are 2-oz copper, and the two internal
layers are 1-oz. copper. The top layer contains the main power traces for VIN, VOUT, and VPHASE. Also on the
top layer are connections for the remaining pins of the TPS54678 and a large area filled with ground. The
bottom and internal layers contain ground planes only. The top-side ground areas are connected to the
bottom and internal ground planes with multiple vias placed around the board including four vias directly
under the TPS54678 device to provide a thermal path from the top-side ground area to the bottom-side
and internal ground planes. The input decoupling capacitors (C1, C2, C3, and C4) and bootstrap capacitor
(C8) are all located as close to the IC as possible. In addition, the voltage set-point resistor divider
components are also kept close to the IC. The voltage divider network ties to the output voltage at the
point of regulation, which is the copper VOUT trace near the output connector, J2. For the TPS54678, an
additional input bulk capacitor, C16, is included to provide lower-source impedance, to yield functionality
that is less dependent on the impedance of the distribution connection to the input supply.

EVALUATION BOARD/KIT/MODULE (EVM)
WARNINGS, RESTRICTIONS AND DISCLAIMERS
For Feasibility Evaluation Only, in Laboratory/Development Environments. Unless otherwise indicated, this EVM is not a finished
electrical equipment and not intended for consumer use. It is intended solely for use for preliminary feasibility evaluation in
laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks
associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end
product.
Your Sole Responsibility and Risk. You acknowledge, represent and agree that:
1.
2.
3.
4.
You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug
Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees,
affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes.
You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable
regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates,
contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical)
between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to
minimize the risk of electrical shock hazard.
You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even
if the EVM should fail to perform as described or expected.
You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials.
Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the
user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and
environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact
a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the
specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or
interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the
load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures
greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include
but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the
EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please
be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable
in electronic measurement and diagnostics normally found in development environments should use these EVMs.
Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives
harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in
connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims
arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected.
Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such
as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices
which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate
Assurance and Indemnity Agreement.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
