Introduction
This user's guide contains background information for the TPS54061 as well as support documentation for
the TPS54061EVM-142 evaluation module (PWR142). Also included are the performance specifications,
the schematic, and the bill of materials for the TPS54061EVM-142.
1.1
Background
The TPS54061 dc/dc converter is designed to provide up to a 0.2A output from an input voltage source of
4.7V to 60V. Rated input voltage and output current range for the evaluation module are given in Table 1.
This evaluation module is designed to demonstrate the small, printed-circuit-board areas that may be
achieved when designing with the TPS54061 regulator. The switching frequency is externally set at a
nominal 400 kHz. The high-side and low-side MOSFETs are incorporated inside the TPS54061 package
along with the gate drive circuitry. The compensation components are external to the integrated circuit
(IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54061 provides
undervoltage lockout inputs. The absolute maximum input voltage is 60V for the TPS54061EVM-142.

Modifications
These evaluation modules are designed to provide access to the features of the TPS54061. Some
modifications can be made to this module.
1.3.1
Output Voltage Set Point
To change the output voltage of the EVM, it is necessary to change the value of resistor R6. Changing the
value of R6 can change the output voltage above 0.8V. The value of R6 for a specific output voltage can
be calculated using Equation 1.
R6 = 10 k W ´
(VOUT - 0.8 V)
0.8 V
(1)
Table 3 lists the R6 values for some common output voltages. Note that VIN must be in a range so that the
minimum on-time is greater than 120ns. The values given in Table 3 are standard values, not the exact
value calculated using Equation 1.

Test Setup and Results
This section describes how to properly connect, set up, and use the TPS54061EVM-142 evaluation
module. The section also includes test results typical for the evaluation module and covers efficiency,
output voltage regulation, load transients, loop response, output ripple, input ripple, and start-up.
2.1
Input/Output Connections
The TPS54061EVM-142 is provided with input/output connectors and test points as shown in Table 4. A
power supply capable of supplying 0.2A 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 0.2A. 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. TP5 is used to monitor
the output voltage with TP6 as the ground reference.

2.10 Powering Up
The start-up waveforms are shown in Figure 14 and Figure 15. In Figure 14, the top trace shows VIN , the
middle trace shows EN, and the bottom trace shows VOUT. The input voltage is initially applied, and when
the input reaches the undervoltage lockout threshold, the start-up sequence begins and the output ramps
up at the externally set rate toward the set value of 3.3V. The input voltage for these plots is 24V with a
16Ω resistive load.

Board Layout

Board Layout
This section provides a description of the TPS54061EVM-142, board layout, and layer illustrations.
3.1
Layout
The board layout for the TPS54061EVM-142 is shown in Figure 18 through Figure 20. The top-side layer
of the EVM is laid out in a manner typical of a user application. The top and bottom layers are 2-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 TPS54061 and a large area filled with ground. The bottom layer
contains ground and a signal route for the BOOT capacitor. The top and bottom and internal ground traces
are connected with multiple vias placed around the board including four vias directly under the TPS54061
device to provide a thermal path from the top-side ground plane to the bottom-side ground plane.
The input decoupling capacitors (C2 and C3), bootstrap capacitor (C4), and frequency set resistor (R3)
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, the copper VOUT trace past the output connector (J2). For the TPS54061, an additional input
bulk capacitor may be required (C1), depending on the EVM connection to the input supply.

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
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
