The switching waveform can be observed on an oscilloscope.

6.

Set the oscilloscope as follows:

Channel 1 sensitivity:

2V/div (at probe tip)

Time base:

1µs/div

Trigger Source:

CH1

Trigger Mode:

Auto

7.

Connect the ground lead of a 10x probe to the supply negative terminal near P2 of the

AL8006EV2, and touch the probe tip onto the anode of D1 as in Figure 2 below. On the

oscilloscope, press RUN/STOP to capture the waveform. The cursor readout indicates a

switching frequency of 440kHz approximately.
