PS3 to Xbox 360 converter help

I need some help here because I cant find this item. At CEO I seen the ATL r3dd used a convert that let him use his PS3 pad on the xbox but it also required his xbox controller to be plugged in. Does anyone know the name of this converter?

Not too saavy on the subject, but this thread is for you: Converter Compatibility Thread

Are you sure that was a PS3 pad and not a PS2 pad?

That’s the xconverter 360. And it’s a ps2 pad. And yes you need a 360 controller plugged in to the connverter.
