Figure 17. Current DAC block diagram
Here you can set the LSB typical current and the relative full scale typical current, then by
writing the DAC value in the text box you can set the amount of current sink by the feedback
pin of the switching regulator.
In this way, after the enabling of the current sink DAC you can obtain an output voltage
higher than the previous one on the VswDrv connector (J9).
3.2.2 How to enable the DC1 and DC2 output bridges
During the startup procedure the bridges are in high impedance status and after they can be
enabled through SPI.
In the first software window click the L6460 device and then the "Bridge 1" or "Bridge 2"
button, the following window then appears (Figure 18).
