4 Performance Data and Typical Characteristic Curves

Figure 4-1 and Figure 4-2 show the efficiency results for the CC and CV channels of the coupled inductor SEPIC controller. The results are shown for different input voltage VIN. It is important to note that the efficiency results include the power loss in the input EMI filter.
