Loop Characteristics
shows the TPS55340EVM-147 loop-response characteristics. Gain and phase plots are shown
for V
IN
voltages of 6V and 18V with load currents of 1A.

Output Voltage Ripple
shows the TPS55340EVM-147 output voltage ripple and inductor current ripple. The output
current is the rated full load of 1A and V
IN
= 6V. The ripple voltage is measured directly across the output
capacitors.
