multi gap inductor core designAbstract: 18122R105K9BB0D Maximum peak current through the core size, but poor efficiency and inductor can be increased up to 7A , compact step down converters, bobbin cores are often used as output inductor. A reference circuit has been modified in order to substitute a bobbin core by a fully gapped IIC. This component is designed , material with a 0.2 mm full gap. The winding has five turns designed on a PCB with 1.7 mm double tracks in , component in the circuit, a bobbin core (Coiltronics UP4B2R2), the IIC shows some distinct advantages with
