LM5010A Macromodel

Varindra,

The LM5010A is available in WEBENCH® Power Designer. You can access it directly from the product folder. Simply enter your VIN, Vout, and Iout and hit the Open Design button:

There is also a quick start calculator (an Excel spreadsheet) for the LM5010A under the Tools section.

Currently, we do not have a macromodel available for the device.

Dear Britt,

                        Thanks. Does anybody know about any equivalent IC of LM5010A.

Kind regards,

Varindra

Hi Britt,

                        Thanks for the suggestion. But We have already made the PCB and looking to replace this IC LM5010MH (after some simulation).

Kind regards,

Varindra

Hi Varindra,

It might be late for your current project, but we did release the LM5010A PSpice model to the product folder today. It should show up after the next update and you could use it for your future projects.

Thanks,

Thanks Nikhil.

Hi,

           I have seen the PSpice model of LM5010, however I do not have the access for cadence tool. Is it possible to simulate the LM5010 using Altium designer. The import option (PSpice model in Altium) generates an encryption error.

Thanks. 

I could get the reply while searching other forums. Please ignore the previous mail.

"Both these models are typically encrypted so they will not run in Altium directly. In case you need the unencrypted model to import into Altium, please work with your local AFA. He/she can help you get these unencrypted models. However, please note that these models are not guaranteed to work in any other simulator other than PSPICE"

Hi,

            I am trying to verify the LM5010 (with a series resistor and zener diode with intended clamp voltage) for ESD regulation, so I had wanted to simulate it. Can anyone please tell any equivalent circuit for the input stage of this regulator so as to simulate with the equivalent instead. I had assumed V_out x I_out = η x V_IN x I_IN for calculating the input resistance while assuming input (and efficiency) at the regulator varies from 15V to 70V and voltage at the output is 5V, current at the output is about 0.6A. Based on this I had calculated the input stage resistance for this regulator.

Just for the information, I had raised the query with TI, Europe support and they have replied as follows:

"Unfortunately we don’t have the unencrypted model for LM5010. You can ask for this specific model in the E2E forum, our engineers may be able to help you."

Kind regards,

Varindra

We now have WEBENCH Altium Connector and WEBENCH Simulation Export into Altium.

Here's some information about WEBENCH Altium Connector: http://blog.live.altium.com/Blogs/ti-webench-release

You need to be on AD14 and above.

First please install the WEBENCH Altium Connector App from inside Altium Extensions and activate it.

Then please go to LM5010A product Folder:

http://www.ti.com/product/lm5010a

and select "Open Design" from inside the WEBENCH(R) LM5010A panel.  This will open WEBENCH design using this part.  You can also select "Simulate Now" to run electrical simulations online using WEBENCH.  To download the simulation schematic into Altium, select "CAD Export" from the WEBENCH Menu Bar and select "Altium Designer" inside the form.  This will download the design SimXML file specific for Altium.  

You can open this file using the WEBENCH Menu (select Open WEBENCH Design) inside Altium.  This will import the WEBENCH SimXML file which contains the simulation schematic, SPICE models, and simulator settings.  You you be using the WEBENCH Simulation Engine which gets installed as part of the WEBENCH Altium Connector App.
