Part Number: AMC1200
Other Parts Discussed in Thread: TINA-TI, ISO5852S

Dear sir,

we are trying to use the AMC1200 PSPICE model available in the website. We are using Orcad 17.2 version.

If we open the model in Orcad, the pin numbers and pin names are not matched.

Kindly we request you to verify the model and update the same.

please find the below part model image and attached model file downloaded from the website.

Thanks & regards,

Rajasekaran.

Hi Rajasekaran,

You can create your own symbol from scratch for the model. See the below documents at Chapter 3:

Dear sir,

Thanks for the guidance. We will try to create the model in PSPICE and simulate it.

This AMC1200 model having the isolation between input and output. The Pspice having only one ground symbol. We are unable to use the two different power source with two different ground. (If we use two ground symbols, they are having the same net names. We want to use two grounds for isolated circuits and they have two different net names in the simulation).

Could you please suggest the suitable procedure to use the isolated power supply for input and output circuit in AMC1200.

Thanking you.

Thanks & regards,

Rajasekaran.

Hi Rajasekaran,

why not running the "AMC1200 TINA-TI reference design"?

Hi,

we can able to run AMC1200 TINA TI model.

We need to simulate ISO5852S and AMC1200 in the same circuit. If we try both in the same circuit, its not running properly. we are getting constant 4.95V as output (from AMC1200).

Could you please suggest me the suitable procedure for running two isolated components in the same circuit.

Thanks & Regards,

Rajasekaran.

Hi Rajasekaran,

I modified the TSC file and I am getting the output voltage ~500mV. I removed the GND1 jumper from input and now input to AMC1200 is given like shown below.

I have attached the TSC file and simulation results below. It seems that AMC1200 is amplifying input voltage.

Please let me know if you have any questions.
