Efficiency and no load measurements
In this section the converter efficiency has been measured at different output current levels
on VOUT1 and VOUT2 fixed at 40 mA and 80 mA.
The figures below show the results.
Figure 8.
Efficiency vs. output power with 3V3 @ 40 mA
Figure 9.
Efficiency vs. output power with 3V3 @ 80 mA
