Part Number: UCC28070

Hi Team,

I would like to change the placement of current transformer(CT) from Case1 to Case2.

If I use UCC28070 at case2, could you please let us know if you have any concern?

Regards,

Hi Hide

The placement of the CStransformer in the source adds the addition inductance of the transformer primary winding into the gate drive circuit which may cause ringing on the fast dv/dt edges of the gate signal.
