The application uses the PMBus protocol to communicate with the controller over serial bus by way of a TI USB adapter (see Figure 5-3). 5.1.2 Features Some of the tasks you can perform with the GUI include: • • • Turn on or off the power supply output, either through the hardware control line or the PMBus operation command. Monitor real-time data. Items such as input voltage, output voltage, output current, and warnings/faults are continuously monitored and displayed by the GUI. Configure common operating characteristics such as VOUT, warning and fault thresholds, and switching frequency.

Connect VIN to J1 as shown in Figure 5-2. 5.2.2 Multimeters • • • • DMM 1: VIN at TP1 (VIN) and TP3 (GND). DMM 2: Input current measured across Shunt 1. DMM 3: VOUT at TP5 (VOUT) and TP17 (GND). DMM 4: Output current measured across Shunt 2. 5.2.3 Output Load The output load should be an electronic constant-resistance mode load capable of 0 ADC to 25 ADC at 1.2 V. An electronic constant-current load is also acceptable. 5.2.4 Oscilloscope A digital or analog oscilloscope can be used to measure the output ripple. To measure output ripple, the oscilloscope should be set for 1-MΩ impedance, 20-MHz bandwidth, AC coupling, 2-µs/division horizontal resolution, 50-mV/division vertical resolution. As shown below in Figure 5-1, test points TP5 and TP17 can be used to measure the output ripple voltage by placing the oscilloscope probe tip through TP5 and holding the ground barrel to TP17. It is not recommended to use a leaded ground connection because this may induce additional noise due to the large ground loop. To measure other waveforms, adjust the oscilloscope as needed. Metal Ground Barrel Probe Tip TP5 TP17 Figure 5-1.

A small fan capable of 200 LFM to 400 LFM is recommended to reduce component temperatures while the EVM is operating at heavy loads. Exercise caution when touching the EVM while the fan is not running, and always exercise caution when touching any circuits that may be live or energized. 5.2.6 Recommended Wire Gauge Input Wires, VIN to J1 (12-V input): The minimum recommended wire size is 1x AWG #14 per input connection, with the total length of wire less than 4 feet (2 feet input, 2 feet return). Maximum input current should be in the order of 3.5 A. Output Wires, J3 and J4 to Load: The minimum recommended wire size is 2x AWG #14, with the total length of wire less than 4 feet (2 feet output, 2 feet return). Maximum output current should be in the order of 20 A. 5.3 Recommended Test Setup Figure 5-2. TPS40400EVM-351 Recommended Test Set Up Figure 5-2 is the recommended test set up to evaluate the TPS40400EVM-351.

Figure 5-3. TPS40400EVM-351 USB-To-GPIO Interface Adapter 5.4.1 Input Connections 1. Prior to connecting the DC input source VIN, it is advisable to limit the source current from VIN to 10 A maximum. Make sure VIN is initially set to 0 V and connected as shown in Figure 5-2. 2. Connect a voltmeter DMM 1 at TP1 (VIN) and TP3 (GND) to measure the input voltage. 3. Connect a voltmeter DMM 2 across shunt to measure the input current. 5.4.2 Output Connections 1. Connect Load between J3 and J4; and set Load to constant-resistance mode to sink 0 ADC before VIN is applied. 2. Connect a voltmeter DMM 3 at TP5 (VOUT) and TP17 (GND) to measure the output voltage. 3. Connect a voltmeter DMM 4 across shunt to measure the output current. SLUU535A – SEPTEMBER 2011 – REVISED JANUARY 2022 TPS40400 Buck Controller Evaluation Module User's Guide Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated 9 Test Setup www.ti.com 5.4.3 Jumper Connections, JP1 and JP2 For most tests it is recommended to install both jumpers, JP1 and JP2 on their respective headers. This will result in the remote sense points (the nodes at which the converter will regulate the output voltage) be located near the output connectors J3 and J4. This configuration is best for most functional testing. These jumpers can be arranged differently depending on the desired location of remote sense. Note The amount of voltage drop between the output connectors J3 and J4 and the remote sense points is limited by the power dissipation in the internal remote sense resistors R7 and R18 (see schematic, Figure 4-1). These resistors are rated for 0.0625 W and are 49.9 Ω. This implies a remote sense voltage drop of no more than 1.7 V in each of the +VE and –VE sense lines. Since this EVM is configured as a 1.2-V output, this will likely not be the limiting factor, but caution is still advised because when remote sense is being utilized, the EVM will attempt to regulate out a lossy load wire installation. Note The EVM may detect an Over-Voltage (OV) condition when remote sensing is being used, depending on the configurable OV setting. Refer to Section 5.2.6 for wire gauge recommendations. When remote sense is not being utilized and the sense points are defaulted to the output connector of the EVM, the voltage drop in the load wires and the resulting reduced voltage applied to the electronic load may cause erratic behavior with the electronic load. This is because many loads will not function properly at input voltages lower than 1 V, which implies no more than 0.2-V drop combined in the load wires (+ and – load wires). Consult the documentation of the electronic load being used. 5.4.4 Jumper Configurations All Jumper selections should be made prior to applying power to the EVM. User can configure this EVM as per following configurations. Table 5-1. Jumper Configurations JUMPERS JP1 AND JP2 DISCRETE SENSE WIRES Installed Do not use Default. Sense points are at the output connectors of the EVM. Most testing. Not installed Sense points are at the output connectors of the EVM, but through R7 and R18. Regulation will be degraded.
