Description
The TPS92561EVM implements a dimming solution using the TPS92561 integrated circuit from Texas
Instruments. The TPS92561 is a boost controller for LED lighting applications utilizing high-voltage, lowcurrent LEDs. The boost converter topology allows the creation of the smallest volume converter possible
as well as enabling high efficiencies beyond 90%. The device incorporates a current sense comparator
with a fixed offset enabling a simple hysteretic control scheme free of the loop compensation issues
typically associated with a boost converter. Integrated overvoltage protection (OVP) and a VCC regulator
further simplify the design procedure and reduce external component count.

Appendix B Layout Considerations
B.1
Hysteretic Boost Converter Layout
Take special care when routing high di/dt and dv/dt traces in order to minimize the conducted and radiated
EMI signature generated by the hysteretic boost converter circuit. A tight loop between the input capacitor,
boost inductor and rectifying diode is recommended to minimize radiated EMI and prevent ground voltage
difference (ground bounce). Please refer to the EVM layout, Figure 17 for further details.

Appendix C EVM Circuit Options Used
C.1
Charge Pump Linear Assist
The TPS92561 data sheet describes methods to provide power to the IC. The method selected for this
EVM uses the 'Linear regulator from output' method, deriving the IC bias voltage from the converter
output. This causes a larger loss in the linear circuitry but provides performance advantages including: a
more consistent turn off and a VP voltage with less variation when dimming. To gain some of the
efficiency loss back, a charge pump is used (C1 and D1), as shown in Figure 1 , to assist the main linear
regulator (Q2, D9, R2, R3, R8) by transferring charge to the bias circuit using a method that incurs lower
losses than if it were derived from the linear regulator directly.
If the value of C1 is too high, the increase in associated switching losses in Q1 will not offset the gains
made by reducing the current draw through the linear. An optimal operation point is reached when the
voltage provided by the charge pump is just slightly higher then the voltage generated by the linear
circuitry. As a good starting point to selecting the C1 value, we consider the current capability of the
capacitance circuit and the current requirements of the IC. The IC uses approximately 1 mA plus the
additional current required to switch the main FET (Qg × fsw). The C1 capacitor can provide a current
based on the capacitance value, the voltage across the capacitor and the frequency of operation:
C u VLED u fsw
(1)
By combining the terms and solving for C1 we obtain:
1 mA + Qg u fsw
C1 =
VLED u fsw
(2)
After a capacitance value is obtained, some fine tuning under typical operating conditions should be
considered as several factors affect the circuit performance including: exact LED voltage, VP bias voltage
(Zener voltage and FET VGS voltage), main FET gate charge requirements, and the variability of the
converter switching frequency. In general the addition of the charge pump circuit can increase the
converter efficiency 1% to 2% when compared to the linear from the output voltage alone. The highest
possible efficiency is still achieved if an auxiliary winding is used to generate the bias voltage.

Line Regulation and Peak Power Limit
C.2
www.ti.com
Line Regulation and Peak Power Limit
The EVM reference (ADJ pin voltage) is generated by dividing down the rectified AC voltage. This is a
very simple method of generating the converter reference, but it also means the reference will change if
the line voltage changes. When considering an LED bulb design for the US or Canadian market, long-term
operation at input voltages that vary greatly from the nominal are not always considered. A simple means
to ensure the LED heat sink temperature will remain controlled is to add this power limiting/line regulation
circuit (R1, R7, D4, C4).
We can first estimate the voltage change at the ADJ pin (our reference voltage) based on the line change
and consider an example for a line change from 120 to 132 VAC.
'VrectAC
132 120 u
2 u .638
10.8 V
(3)
Equation 3 gives us the average change in the average rectified AC voltage of approximately 10.8 V. We
can apply this to our divider based on R9 and R17:
10.8 u R17
'V_ADJ =
| 140 mV
R9 R17
(4)
The Zener was selected as 110 V based on the average rectified AC voltage for 120 VAC of 108 V.
Next we can design our compensation circuit to apply that same voltage offset when the average rectified
AC voltage increases. Based on the circuit designators R1, D4, R7, R12 and the combination of R15 and
R16 we can solve for the series resistance required to provide the current required to apply an offset
voltage equal to the amount change due to the line. A simplified expression can be used:
R_total =
V_high_line u 0.9 Vz
'V _ ADJ y R12
586 k:
(5)
Equation 5 represents the total resistance of R1 + R7. The resistance should be split with a heavy bias to
R1 limiting the voltage ripple on C4. After the circuit is in place, a few tests should be completed to allow
fine tuning of the resistance values. This simplified approach did not account for the smaller variation from
the conversion itself (given that the converter is controlling the input current, not the output current by the
relationship:

Vin u Iin =

CSA, VDE, CE, RoHS and WEEE) which may normally be associated with similar items. You assume full responsibility to determine
and/or assure compliance with any such standards and related certifications as may be applicable. 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
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 as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
