Test Equipment
www.ti.com
5 Test Equipment
Voltage Source: The input voltage source VIN must be a 0-V to 18-V variable DC source capable of supplying
at least 12 ADC.
Multimeters: It is recommended to use two separate multimeters Figure 6-1. One meter is used to measure VIN
and one to measure VOUT.
Output Load: A variable electronic load is recommended for testing Figure 6-1. It must be capable of 40 A at
voltages as low as 0.6 V.
Oscilloscope: An oscilloscope is recommended for measuring output noise and ripple. Output ripple must
be measured using a tip-and-barrel method or better as shown in Figure 6-2.The scope must be adjusted to
20-MHz bandwidth, AC coupling at 50 mV/division, and must be set to 1-µs/division.
Fan: During prolonged operation at high loads, it may be necessary to provide forced air cooling with a small fan
aimed at the EVM. Temperature of the devices on the EVM must be maintained below 105°C.
Recommended Wire Gauge: The voltage drop in the load wires must be kept as low as possible in order to
keep the working voltage at the load within its operating range. Use the AWG 14 wire (2 wires parallel for VOUT
positive and 2 wires parallel for the VOUT negative) of no more than 1.98 feet between the EVM and the load.
This recommended wire gauge and length should achieve a voltage drop of no more than 0.2 V at the maximum
40-A load.

5.
Connect VOUT to J3 and VOUT_GND to J5 Figure 6-1.
Ensure that the electronic load is set to draw 0 ADC.
Connect VIN to J1 and VIN_GND to J2 Figure 6-1.
Increase VIN from 0 V to 12 V using the digital multimeter to measure input voltage.
Use the other digital multimeter to measure output voltage VOUT at TP2 and TP10.

6. Vary the load from 0 ADC to maximum rated output 40 ADC. VOUT must remain in regulation as defined in
Table 3-1.
7. Vary VIN from 5 V to 16 V. VOUT must remain in regulation as defined in Table 3-1.
8. Decrease the load to 0 A.
9. Decrease VIN to 0 V or turn off the supply.
8.2 Efficiency
To measure the efficiency of the power train on the EVM, it is important to measure the voltages at the correct
location. This is necessary because otherwise the measurements will include losses in efficiency that are not
related to the power train itself. Losses incurred by the voltage drop in the copper traces and in the input and
output connectors are not related to the efficiency of the power train, and they must not be included in efficiency
measurements.

Input current can be measured at any point in the input wires, and output current can be measured anywhere
in the output wires of the output being measured. Using these measurement points result in efficiency
measurements that do not include losses due to the connectors and PCB traces.
