9.1 Application Information

This control device is generally applicable to the control of AC-DC power supplies which require Active Power Factor Correction off Universal AC line. Applications using this device generally meet the Class-D equipment input current harmonics standards per EN61000-3-2. This standard applies to equipment with rated Powers higher than 75W. The device brings two phase interleaved control capability to the Transition Mode Boost and hence will be generally a very good choice for cost optimized applications in the 150W to 800W space, or to even lower powers that wish to leverage on the interleaving benefits of reduced filtering component size, lower profile solutions and distributed thermal management.
