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
