CRD-30DD12N-K reference design : datasheet for the 20W flyback transformer (T12)

gkim

Hello,

With respect to the reference design of CRD-30DD12N-K, we are going to build the auxiliary power board by using the PCB design file of CRD0600XX Aux Power board Ver 02.brd.

Meanwhile, I need the datasheet for the 20W flyback transformer (T12); its manufacturer P/N is EE19-20W.

Would you please share the datasheet for the 20W flyback transformer (T12)?

I need to make this issue clear before I send the gerber data to the PCB house.

Thank you for your consideration.

With regards,

GKIM

Hello GKIM,

please find the datasheet as attached. please note that it is designed for demo. you may need to modify/verify it for production.

Regards,

Hi FrankWei,

Thank you for sharing the datasheet for the Flyback transformer.

After reviewing the datasheet, I have a question on the datasheet.

The parameter of Induction(2-1) is specified as 13uH nominally.

I suppose that the parameter of Induction(2-1) represents the inductance of the coil wound from Terminal 2 to Terminal.

If this is the case, the winding stack up in the datasheet looks weird to me.

There are two sections of N10 in the winding stack up, and the coil wound from Terminal 1 to Terminal 3 is associated with the section N10.

Is this mean that one section of N10 is associated with the coil wound from Terminal 1 to Terminal 2 and the other section of N10 is associated with the coil wound from Terminal 2 to Terminal 3?

Thank you for your consideration.

With regards,

GKIM
