Click the "Switching Reg. controller" button, the "Switching Regulator controller" window
then appears
Figure 15. Switching regulator controller
To obtain the output voltage of 12 V as prearranged (VSupply = 24 V), do the following (see
Figure
1.

Figure 16. Enable switching regulator controller
If you want to increase the output voltage you can act on the reference voltage of the
feedback, for example if you raise it to 1 V by clicking the "+" button close to the value, the
output voltage rises by about 25%.
In this demonstration board, it is possible to change the VswDrv voltage using the internal
multiple range 6-bit current sink DAC.
The DAC output is connected to GPIO8, and then in order to use it to change the VswDrv
voltage, the JP8 must be closed (VSWDRV_FB connected to GPIO8).
In the first software window click the L6460 device and then the "Current DAC" button, the
following window appears
Raise the duty cycle of the generated pulse to 58% by clicking the "+" button close to
the value
Tick the "Enable" auto-check box, the VswDrv then turns-on.
