4 Test Setup and Procedure
4.1 Test Setup
Figure 3 shows the correct jumper positions to configure the evaluation module for the typical application,
as shown in Figure 1. The correct equipment connections and measurement points are shown in Table 3
Table 3. Standard Configuration Jumper Connections
Jumper Position
J6 Jumper from pin 2 to pin 3
Figure 3. Test Setup
4.2 Test Equipment
Power Supply: The input voltage source (VIN) should be a variable supply capable of 0V to 20V and
source at least 15A.
Multi-meters:
• Voltmeter 1: Input voltage, connect from VIN to VIN-
• Voltmeter 2: Output voltage, connect from VOUT to GND
• Ammeter 1: Input current, must be able to handle 15A. Shunt resistor can be used as needed.
• Ammeter 2: Output current, must be able to handle 3A. Shunt resistor can be used as needed.
Electronic Load: The load should be constant resistance (CR) or constant current (CC) capable. It should
safely handle 3A at 12V.
Oscilloscope: 20-MHz bandwidth and AC coupling. Measure the output voltage ripple directly across an
output capacitor with a short ground lead. It is not recommended to use a long-leaded ground connection
due to the possibility of noise being coupled into the signal. To measure other waveforms, adjust the
oscilloscope as needed.

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.

3.1 United States
3.1.1 Notice applicable to EVMs not FCC-Approved:
FCC NOTICE: This kit is designed to allow product developers to evaluate electronic components, circuitry, or software
associated with the kit to determine whether to incorporate such items in a finished product and software developers to write
software applications for use with the end product. This kit is not a finished product and when assembled may not be resold or
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.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
