F. Design-Loop Panel
This panel can determine the load point to enter burst mode by configuring Burst Mode Load. Kp
and Ki of closed-loop control can also be set (see Figure 17).
If Set-Up Mode is set to
“Auto,” Kp and Ki are kept at their defaults.
If Set-Up Mode is set to
“Manual,” Kp and Ki can be changed. Related bode plots are drawn to
help check gain and phase margin of the loop.
