The same operation can also be done via the I
C interface panel by selecting the register address,
the data to send and pressing the Send button. A read-back can be performed by clicking the Read
button, see
Figure

After enabling the BUCKA converter it is possible to monitor the output voltage on the PCB via an
external multi-meter connected to the VOUT_A pin, as shown in
Figure
7. The read-back should
provide a value close to 1.0 V. If the part is not trimmed the value can slightly differ from the target.
It is also possible to directly monitor some relevant signals on the PCB, for example, the inductor
current of each phase.
