Be sure to apply the input voltage to the EVM prior tolaunching the software. This sequence ensures that the controller and GUI recognize each other.5.1Configuration Procedure1.2.3.4.Adjust the input supply to provide 5 VDC, current limited to 1 A.Apply this input voltage to the EVM. Refer to Figure 11 and Figure 12 for connections and test setup.Launch the Fusion GUI software. Refer to the screenshots in Section 10 for more information.Configure the EVM operating parameters as desired.6Test Procedure6.1Line/Load Regulation and Efficiency Measurement Procedure1. Set up EVM as described in Figure 11.2. Ensure the electronic load is set to draw 0 Adc.3. Increase 5VIN from 0 V to 5 V.4. Increase VIN from 0 V to 12 V.5. Put switch S1 to ON position.6. Vary the load from 0 Adc to 120 Adc. Ensure VOUT remains in regulation as defined in Table 1.7. Vary VIN from 8 V to 14 V. Ensure VOUT remains in regulation as defined in Table 1.8. Decrease the load to 0 A.9. Put switch S1 to OFF position.10. Decrease VIN to 0 V.11. Decrease 5VIN to 0 V.6.2Control Loop Gain and Phase Measurement ProcedureThe PWR710 EVM includes a 0-Ω series resistor R64 in the feedback loop. This resistor value can bechanged to 10 Ω and then be used for loop response analysis, which is accessible at the connector J7and J8. These two connectors should be used during loop response measurements as the injection pointsfor the loop perturbation.

Test Procedurewww.ti.comTable 5. Test Points for Loop Response Measurements6.2.11.2.3.4.5.6.7.6.3TEST POINT NODENAMEDESCRIPTIONCOMMENTJ8 INPUTInput to feedback of VOUTThe amplitude of the perturbation at thisnode should be limited to less than 100 mV.J7 OUTPUTResulting output of VOUTBode can be measured by a networkanalyzer as J7 or J8 .ProcedureSet up EVM as described in Figure 11.Connect the network analyzer isolation transformer from J8 to J7 .Connect the input signal measurement probe to J8 .Connect output signal measurement probe to J7 .Connect the ground leads of both probe channels to J7– or J8–.On the network analyzer, measure the Bode as J7 or J8 (Out or In).Disconnect the isolation transformer from the bode plot test points and change the resistor R64 back to0 Ω before making other measurements, because the signal injection into the feedback loop mayinterfere with the accuracy of other measurements.EfficiencyIn order to measure the efficiency of the power train on the EVM, it is important to measure the voltages atthe correct location. This is necessary because otherwise the measurements will include losses that arenot related to the power train itself. Losses incurred by the voltage drop in the copper traces and in theinput and output connectors are not related to the efficiency of the power train, and they should not beincluded in efficiency measurements.Input current can be measured at any point in the input wires, and output current can be measuredanywhere in the output wires of the output being measured.Figure 13 shows the measurement points for input voltage and output voltage. Using these measurementpoints results in efficiency measurements that do not include losses due to the connectors and PWBtraces.12Using the TPS53647: PWR710-EVM, 4-Phase, D-CAP Step-Down, DC-DCAnalog with PMBus InterfaceCopyright 2015, Texas Instruments IncorporatedSLUUBA9 – June 2015Submit Documentation Feedback
