Coil [ SC2912] of Sumida corporation is used in this module.

Do you know why this coil is selected?

Mitsuo,

The Sumida core was design with the slot for the DRV421 to easily be placed within close proximity to the core. Are you in need of a core of different specifications?

Javier Contreras

Hi Javier,

This is Stewart from Korea.
Plase share the SC2912-15 datasheet with me and why used the 4:1 transfomer.

Thanks..

Stewart,

I will see what I can get from Sumida who manufactured this core. On the 4:1 transformer I assume you are referencing the 4 conductors on the picture. Those are conductors are in parallel so they would only be one primary winding and the secondary is at 966 windings which are internal and are not visible.

Regards,

Javier

Hi,

where can i buy a core with a slot for the DRV421 Evaluation Module?
I want to buy the Evaluation Module, but I could not find a suitable magnetic core.

Yours,
Christoph

Hello Christoph,

There is currently not a core off the self with a slot that fits the DRV421 Evaluation Module. I can help you with the design of the magnetic core and go over your design considerations to meet you needs.
