Output Voltage Ripple
shows the EVM output voltage ripple. The output current is the rated full load of 6 A and V
IN
= 3.0
V. The ripple voltage is measured directly across the output capacitors.
Figure 7. TPS54678EVM-155 Output Ripple at V
IN
= 3.0 V and 6 A
shows the ripple at 6 A and V
IN
= 6.0 V. The ripple voltage is measured directly across the output
capacitors.
