Loop Characteristics
shows the EVM loop-response characteristics. Gain and phase plots are shown for V
IN
voltage of
3.6 V with load current of 2.1 A.

Output Voltage Ripple
shows the EVM output voltage ripple and inductor current ripple. The output current is the rated
full load of 2.1 A and V
IN
= 3.6 V. The ripple voltage is measured directly across the output capacitors.
