After calculating the SEPIC converter topology, the program suggests the inductors which fit best electronically into the circuit. The list can then be further optimized by taking DCR or mechanical dimensions into consideration. Below, the example with a coupled inductor pre-setting shows an example using two individual inductors. The inductance value of the coupled inductor is exactly half of the individual inductor. In this example, it is clearly shown that by choosing a coupled inductor, the DCR can be reduced significantly (67mOhm vs. 2x72mOhm). All products shown in the inductor selector tool are catalog products. For Wurth Electronics, this means available in stock, short lead times for production volume and outstanding quality. All products are also stocked at Digi-Key. 14
In Summary, a SEPIC converter is used in applications with a flexible input voltage range, which needs a stable output of a certain voltage. Such applications are battery operated devices, NiMH chargers and LED driver applications. Wurth Electronics is offering a full range of coupled inductors for such applications: WE-DD, WE-TDC and WE-DCT series. All products shown are available in stock at digikey.com. Additionally, Wurth Electronics offers an easy-to-use design software for magnetics design, which allows calculation of a coupled inductor for a SEPIC converter within seconds. 15
