DRV421EVM: Magnetic core with slot cut

Part Number: DRV421EVM
Other Parts Discussed in Thread: DRV421

Hi everyone,

we have ordered some evaluation boards from TI and would like to test out this chip DRV421. But we have problem to find proper manufactory for this special core. As it is discribed in the application note, there must be a slot cut inside the core, and the magnetic characteristik from the core shall not be distroyed during the manufacture. Could TI provide this core? Thanks in advance.
