TPS62067 Spice model

Other Parts Discussed in Thread: TPS62067

I have downloaded te Spice model of TPS62067 and during simulation there is a 740mA current drawn at teh Avin pin when

TPS62067 EN pin is tie to Vin
TPS62067 EN pin is tie to ground

This should not be correct but can someone help to verify if there is a mistake in the Spice model or this is the actual performance of the IC?

Hi,
You're right. I will check this with modeling group and come back to you.

Usually the pspice models do not accurately model the input voltage pins of the device. I forget the technical term of the input block that is used, but the current draw is not accurate. You cannot for instance model the efficiency of the converter because of this.
