5 Test Setup
5.1 Equipment
5.1.1 Voltage Source
VIN: The input voltage source (VIN) should be a 0-V to 20-V variable DC source capable of 20 ADC.
5.1.2 Meters
A1: 0 ADC to 20 ADC, ammeter
V1: VIN, 0-V to 20-V voltmeter
V2: VOUT, 0-V to 5-V voltmeter
5.1.3 Loads
LOAD1: The output load (LOAD1) should be an electronic constant current mode load capable of 0 ADC to 20
ADC at 3.3 V.
5.1.4 Oscilloscope
Oscilloscope: A digital or analog oscilloscope can be used to measure the ripple voltage on VOUT. It is
also used to monitor various test points around the EVM. Section 6 describes test procedure for these
measurements. For ripple measurements it is not recommended to use the leaded ground connection supplied
with the oscilloscope. This can induce additional noise due to the large ground loop area.
5.1.5 Signal Generator
A signal generator can be used to synchronous the EVM to a higher switching frequency. See Section 6 for
details on doing this.
5.1.6 Recommended Wire Gauge
VIN to J1: The connection between the source voltage, VIN and J1 of the EVM can carry as much as 20 ADC.
The minimum recommended wire size is 2x AWG #16 with the total length of wire less than two feet (2-feet
input, 2-feet return).
J3 and J4 to LOAD1 (Power): The power connection between J2 of the EVM and LOAD1 can carry as much
as 20 ADC. The minimum recommended wire size is 2x AWG #16, with the total length of wire less than two feet
(1-foot output, 1-foot return).

5.1.7 Other
Fan: This evaluation module includes components that can get hot to the touch, because this EVM is not
enclosed to allow probing of circuit nodes, a small fan capable of 200 LFM to 400 LFM is required to reduce
component surface temperatures to prevent user injury. The EVM should not be left unattended while powered.
The EVM should not be probed while the fan is not running.

5.2 Equipment Setup
Shown in Figure 5-1 is the basic test setup recommended to evaluate the TPS40195EVM. Please note that
although the return for J1 and J4 are the same, the connections should remain separate as shown in Figure 5-1.
1. Working at an ESD workstation, make sure that any wrist straps, bootstraps, or mats are connected
referencing the user to earth ground before power is applied to the EVM. Electrostatic smock and safety
glasses should also be worn.
2. Prior to connecting the DC input source, VIN, it is advisable to limit the source current from VIN to 20-A
maximum. Make sure VIN is initially set to 0 V and connected as shown in Figure 5-1.
3. Connect the ammeter A1 (0-A to 20-A range) between VIN and J1 as shown in Figure 5-1.
4. Connect voltmeter V1 to TP1 and TP2 as shown in Figure 5-1.
5. Connect LOAD1 to J3 and J4 as shown in Figure 5-1. Set LOAD1 to constant current mode to sink 0 ADC
before VIN is applied.
6. Connect voltmeter, V2 across TP5 and TP6 as shown in Figure 5-1.
7. Place Fan as shown in Figure 5-1 and turn on, making sure air is flowing across the EVM.

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.
