3.6 Performance Characteristics
Figure 7 shows the efficiency curves. During the efficiency measurement, monitor the current into and out
of the evaluation board and monitor the voltage directly at the input and output terminals of the evaluation
board.

3.7 Board Configuration
3.7.1 Loop Response
TP6 and TP7 have been provided in order to measure the loop transfer function. For detail information
about the loop transfer function measurement, see AN-1889 How to Measure the Loop Transfer Function
of Power Supplies (SNVA364).
