changes with input changes. Also, you can see these mode changes by attaching a
scope probe to the “CF1P” post and observe how the pump waveform changes from the
2X mode to the 1.5X mode, as shown in the scope traces shown below. As seen in the
datasheet specification for Power Efficiency, by dynamically changing modes with input
voltages the SP6680 optimizes power efficiency.
