performance and reliability.
Sidebar: Modules can still
be highly efficient
Modules should not compromise
power converter performance and
much less their efficiency, which
needs to be as high as possible to
reduce power losses and issues with
heat dissipation. The efficiency plot of
the XR79206 in figure 5 below shows
it achieving almost 95% efficiency at
a 700KHz switching frequency. Figure
6 further illustrates how the module
switches mode briefly from DCM
to CCM operation to execute a fast
transient response before returning
back to DCM to save power.
Figure 6. The XR79206 executes
a load step from 0.05A to 3A by
seamlessly changing from DCM
to CCM
