2.7 Output Voltage Ripple
The TPS54x73EVM-225 output voltage ripple is shown in Figure 2–13 and
Figure 2–14 for each device type. The input voltage is 3.3 V for the TPS54673.
The input voltage is 5 V for the TPS54873. Output current for each device is
the rated full load. Voltage is measured directly across output capacitors.
