Background
The TPS55340 DC/DC converter is in typical applications a step-up boost converter, however this EVM
uses it in a SEPIC topology. Rated input voltage and output current range for the evaluation module are
given in Table 1. This evaluation module demonstrates the performance of the TPS55340 in an example
application and can accommodate evaluation of other SEPIC applications supported by the TPS55340.
This design shows a small printed-circuit-board area that can be achieved when designing with the
TPS55340 regulator. However, appropriate sizing of the inductor and diode for the desired application can
further reduce the board area. The switching frequency is externally set at a nominal 500kHz. The 40V,
5A, low-side MOSFET is incorporated inside the TPS55340 package along with the gate drive circuitry.
The low drain-to-source on-resistance of the MOSFET allows the TPS55340 to achieve high efficiencies.
The compensation components are external to the integrated circuit (IC). In this example application the
absolute maximum input voltage for the TPS55340EVM-147 is 26V.

Modifications
These evaluation modules provide access to the features of the TPS55340. Some modifications to this
module are possible.
3.1 Output Voltage Set Point
The resistor divider network of R1 and R2 sets the output voltage. Keep R2 fixed at or close to 10kΩ. To
change the output voltage of the EVM, change the value of resistor R1. Calculate the value of R1 for a
specific output voltage by using Equation 1.
10kꢀ×1.229V
R1=
VOUT -1.229V
(1)
Note that VIN must be in a range so that the on-time is greater than the minimum controllable on-time
(77ns typical), and the maximum duty cycle is less than 89% minimum and 93% typical.
After adjusting the output voltage the maximum input voltage must be taken into consideration. The
voltage on the internal FET, the SW pin, is equal to the sum of the input voltage and the output voltage.
By using Equation 2 you can determine the recommended maximum input voltage.
V max=38V-VOUT
IN
(2)
3.2 Maximum Output Current
After adjusting input or output voltage settings, verify the maximum output current per Equation 3 below,
where ILIM is the peak current limit of the TPS55340 and VF is the forward voltage drop of the external
schottky diode (D1). This equation combines Equations 40, 42, and 44 from the datasheet.

3.3 Slow-Start Time
The slow-start time can be adjusted by changing the value of C3. The EVM uses C3 = 0.047 µF as
recommended on the data sheet to avoid any overshoot during start-up. A larger capacitance increases
the slow-start time while a smaller capacitance decreases it.
3.4 Other Modifications
Please see data sheet recommendations and equations when changing the switching frequency,
input/output voltage range, input inductor, output capacitors or compensation.

4.1 Input/Output Connections
The TPS55340EVM-147 is provided with input/output connectors and test points as shown in Table 3.
Connect a power supply capable of supplying 5A to J6 through a pair of 20 AWG wires. The jumper
across JP1 in the ON position (1-2) must be in place. Connect the load to J7 through a pair of 20 AWG
wires. The maximum load current capability must be at least 1A. Wire lengths must be minimized to
reduce losses in the wires. Header J1 provides a place to monitor the VIN input voltages with J3 providing
a convenient ground reference. Use J2 to monitor the output voltage with J4 as the ground reference.

Board Layout
This section provides a description of the TPS55340EVM-147 board layout and layer illustrations.
5.1 Layout
The board layout for the TPS55340EVM-147 is shown in Figure 17 through Figure 21. The top-side layer
of the EVM is laid out in a manner typical of a user application. The top, bottom, and internal layers are 2-
oz. copper.
The top layer contains the main power traces for VIN, VOUT, and SW. Also on the top layer are connections
for the remaining pins of the TPS55340 and a large area filled with ground. The internal layers and bottom
are primarily ground with additional fill areas for VIN, and VOUT. The top-side ground traces connect to the
bottom and internal ground planes with multiple vias placed around the board. Nine vias directly under the
TPS55340 device provide a thermal path from the top-side ground plane to the bottom-side ground plane.
Place the output decoupling capacitors (C8-C11) as close to the IC as possible. The copper area of the
SW node is kept small to minimize noise. The vias near the diode D1 on the VOUT plane aid with thermal
dissipation. Additionally, keep the voltage setpoint resistor divider components close to the IC. The voltage
divider network ties to the output voltage at the point of regulation, the copper VOUT trace at the J7 output
connector. For the TPS55340, an additional input bulk capacitor may be necessary, depending on the
EVM connection to the input supply. Critical analog circuits such as the voltage setpoint divider, frequency
set resistor, slow-start capacitor, and compensation components terminate to ground by using a separate
ground trace on the top and bottom connected power ground pour only at one point directly under the IC.

1. 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.
2. 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.
3. 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.
4. 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
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.
