1 Description
The TPS51513EVM-549 is designed to use a regulated 12-V (8-V to 14-V) bus to produce a high-current,
regulated variable output at up to 20 A of the load current. The output voltage varies from 0.70 V to 1.05
V through a 3-bit VID digital-to-analog converter (DAC). The TPS51513EVM-549 is designed to demonstrate
the TPS51513 in a typical low-voltage application while providing a number of test points to evaluate the
performance of the TPS51513.

Test Setup
www.ti.com
4 Test Setup
4.1 Test Equipment
Voltage Source: The input voltage source, VIN, must be a 0-V to 14-V variable DC source capable of supplying
10 ADC. Connect VIN to J1 as shown in Figure 4-2.
Multimeters: A 0-V to 14-V voltmeter (V1) must be used to measure VIN at TP1 (VIN) and TP2 (GND). A 0-V to
5-V voltmeter (V2) is necessary for VOUT measurement at TP5 (VOUT) and TP8 (GND). A 0-A to 10-A current
meter (A1) as shown in Figure 4-2 is used for input current measurements.
Output Load: The output load must be an electronic constant resistance mode load capable of 0 ADC to 30 ADC
at 1.05 V.
Oscilloscope: A digital or analog oscilloscope can be used to measure the output ripple. The oscilloscope must
be set for the following:
•
•
•
•
•
1-MΩ impedance
20-MHz bandwidth
AC coupling
2-µs/division horizontal resolution
20-mV/division vertical resolution
Test points TP5 and TP8 can be used to measure the output ripple voltage by placing the oscilloscope probe tip
through TP5 and holding the ground barrel TP8 as shown in Figure 4-1. Do not use a leaded ground connection
as this may induce additional noise due to the large ground loop.
Metal Ground Barrel
Probe Tip
TP5
TP8
Figure 4-1. Tip and Barrel Measurement for VOUT Ripple
Fan: Some of the components in this EVM may get hot and approach temperatures of 60°C during operation. A
small fan capable of 200 LFM–400 LFM is recommended to reduce component temperatures while the EVM is
operating. The EVM must not be probed if the fan is not running.
Recommended Wire Gauge: For VIN to J1 (12-V input) the recommended wire size is AWG 14 per input
connection, with the total length of wire less than four feet (2-foot input, 2-foot return). For J2, J3 to LOAD, the
minimum recommended wire size is 2× AWG 14, with the total length of wire less than four feet (2-foot output,
2-foot return)

Figure 4-2. TPS51513EVM-549 Recommended Test Setup
Figure 4-2 is the recommended test setup to evaluate the TPS51513EVM-549. Working at an ESD workstation,
ensure that any wrist straps, bootstraps, or mats are connected, referencing the user to earth ground before
handling the EVM.
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. Ensure that VIN is initially set to 0 V as shown in Figure 4-2.
2. Connect a voltmeter V1 at TP1 (VIN) and TP2 (GND) to measure the input voltage.
3. Connect a current meter A1 between VIN DC source and J1.
Output Connections
1. Connect Load to J2, J3, and set Load to constant resistance mode to sink 0 ADC before VIN is applied.
2. Connect a voltmeter V2 at TP5 (VOUT) and TP8 (GND) to measure the output voltage.
Other Connections:
Place a fan as shown in Figure 4-2, and turn it on, ensuring that air is flowing across the EVM.
