Application circuit
In Figure 26 is shown the demonstration board application circuit working.
The operating switching frequency is 400 kHz. The designed system bandwidth is 68 kHz
with a the phase margin of 50
°. The peak current limitation is set 5.2 A, the valley current
limitation 5.8 A in order to deliver up to 4 A DC to the load.
