4. Design Tools
The Si8250DK development kit (Figure 3) contains
everything required to develop applications with the
Si825x family of digital power controllers. This kit
supports all phases of power supply development from
controller design through real-time system debugging. It
also includes a turnkey, 35 W isolated dc/dc target
board for evaluation and experimentation.

The tool set enables users to configure pre-written
application software included in the kit to their
application using a set of PC-based graphical user
interface (GUIs). These GUIs (Figures 4 and 5) allow
the user to quickly and easily specify and verify system
timing, loop compensation, and protection settings and
compile and download the resulting code into the
Si8250/1/2 (Figure 6).
