Test Setup
5.1
Test Equipment
Voltage Source: The input DC voltage source (VSOURCE) shall be a 0-V to 15-V variable DC source
capable of 10 ADC at 4.5 VDC. Connect VSOURCE to J1 as shown in Figure 2.
Multimeters:
• Volt meter, V1: 0 VDC to 15 VDC for input voltage measurement.
• Volt meter, V2: 0 VDC to 5 VDC for output voltage measurement.
• Current meter, A1: 0 VDC to 10 ADC for input current measurement.
• Current meter, A2: 0 ADC to 30 ADC for output current measurement.
• Current shunt: a resistive shunt (i.e. 1-V/100-A shunt) may be used instead of A2 to monitor the
output current. When using a resistor shunt, a volt meter, V3, shall be used to measure the voltage
drop across the shunt in order to monitor the output current.
Output Load: Load, an electronic constant current mode load capable of 0 ADC to 30 ADC at 1.2 V shall be
used for LOAD
Oscilloscope: A digital or analog oscilloscope can be used to measure the ripple voltage on VOUT. The
oscilloscope should be set for 1-MΩ impedance, 20-MHz bandwidth, AC coupled. Test points TP8 and
TP20 or test points TP7 and TP22 can be used to measure the ripple on VOUT. Use the tip and barrel
method sown in Figure 2 to avoid inducing additional noise due to the large ground loop area that would
result from using the probes ground lead.
Recommended Wire Gauge:
• VSOURCE to J1: The connection from VSOURCE to the J1 connector of the EVM can carry as much as 10
ADC. The wire gauge shall be 14 AWG minimum and no longer than 2 feet for each connection,
VSOURCE+ to J1+, and VSOURCE- to J1-.
• EVM to LOAD: The connection from J3 of the EVM to the LOAD can carry as much as 30 ADC. The
wire gauge shall be two 10 AWG wires in parallel and no longer than 2 feet for each connection, J3 to
Load+, including the current meter or the shunt, and LOAD- to J5.
Fan: This evaluation module includes components that can get hot to the touch. A small fan capable of
200 LFM to 400 LFM is required at all times during testing.
5.2
Recommended Test Setup
Shown in Figure 2 is the basic test set up recommended to evaluate the TPS40322EVM-074.
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.
• Input connections: Prior to connecting the DC input source, VSOURCE, it is advisable to limit the source
current from VSOURCE to 10 A maximum. Make sure VSOURCE is initially set to 0 V and connected as
shown in Figure 2.
• Output connections: Connect Load to J3 and J5, as shown in Figure 2. Set LOAD to constant current
mode to sink 0 A before VSOURCE is applied. Connect voltmeter V2 across TP3 and TP4 as shown in
Figure 2.
If using a shunt to monitor output current, connect the shunt in series with LOAD and connect
voltmeter V3 across it to monitor the output current.
• Other connections: Place Fan as shown in Figure 2 and turn on, making sure air is flowing across the
EVM at all times.

Test Procedure
6.1
Load Regulation Measurement Procedure
1. Ensure the LOAD is set to constant-current mode and to set to sink 0 A.
2. Increase VSOURCE from 0 V to 4.5 VDC. VOUT should be in regulation once V1 shows VIN is 4.5 V or
greater.
3. Vary LOAD from 0 A to 30 A. VOUT should remain within regulation per Table 1.
6.2
Line Regulation Measurement Procedure
1. Set LOAD to constant-current mode and to set to sink 30 A.
2. Vary VSOURCE so that V1 measures 4.5 VDC to 15.0 VDC. VOUT should remain within regulation per
Table 1.
6.3
Control Loop Gain and Phase Measurement Procedure
1. Connect a 1-kHz to 1-MHz isolation transformer to CHA and CHB, referenced to TP15.
2. Connect the input signal amplitude measurement probe (Channel A) to CHA with the ground lead
connected to TP15.
3. Connect the output signal amplitude measurement probe (Channel B) to CHB with the ground lead
connected to TP15.
4. Inject a 25-mV, or less, signal across CHA and CHB through the isolation transformer.
5. Sweep the frequency from 100 Hz to 1 MHz with 1-Hz or lower post filter.
6. Control loop gain can be measured by 20 x LOG(ChB/ChA)
7. Control loop phase is measured by the phase difference between ChA and ChB.
8. Disconnect the isolation transformer from the EVM before making other measurements. The signal
injection into the feedback may interfere with the accuracy of other measurements.
6.4
Enabling/Disabling the Outputs
1. The User may disable the output by shorting TP13 (EN/SS) to ground.
2. Enable the output by removing the short from TP13 (EN/S) and leaving TP13 open.
6.5
Equipment Shutdown
1. Shut down LOAD.
2. Shut down VSOURCE.
3. Shut off fan.
