Hi I design a dc to dc board ,that has an inductor of 47Uh , 5A ,when I use a Ring ferrite core, it doesn't get too hot .for simplicity, I used the design EE16 core , but it gets very hot. what is the problem? Do you have any Idea? Attached photo. |

The wire appears to be on the thin side. Please post a schematic. |

Is the core gapped? What is the core material? |
| alizare368:
hi thank you for your help. the core doesn't gap and the core material is ferrite . |

There are many different types of ferrite cores. Some will need a different frequency. Some will not work at all. Your E inductor core is much smaller than your ring inductor core. It maybe that the E core is too small to handle that much current. Ring cores are very efficient shape, to get the same performance from an E core it needs to be bigger. |
