In case dual inductor options do not offer high enough power ratings for the design, a Versa-Pac product family can be used to enable more options. This product family offers five different sizes of configurable parts. Each size is offered with several different core gap options ranging from ungapped cores for use in transformers, to gapped cores for use in SEPIC converter applications. Each Versa-Pac device has six independent windings that can be configured in series or parallel to provide a very wide range of inductance or current ratings. Because this product family has over five hundred configurations, it is quicker to use the online Excel calculator to select the proper part. When the parameters of the SEPIC design are entered, the calculator returns with the optimum part number and will even tell how to connect the windings when a Versa-Pac product is recommended.
