After calculating the SEPIC converter topology, the program suggests the inductors which best fit electronically into the circuit. This list can then be further optimized by taking DCR or mechanical dimensions into consideration. In the examples, a coupled inductor pre-setting shows an example using two single inductors. The inductance value of the coupled inductor is exactly half of the single inductor. It is clearly shows that by choosing a coupled inductor, the DCR can be reduced significantly (67 mOhm Vs. two 72 mOhm). All products shown in the inductor selector tool are catalog products. For Würth Elektronik, this means available in stock, short lead times for production volume and outstanding quality. All products are also stocked at DigiKey.
