Part Number: PMP40285
Hi,
My customer is just considering the PMP40285.
Could you provide the EMI data of this design if you have?

Part Number: LM73606
Tool/software:
Dear members,
I´m having troubles with the simulation of LM73606 with the reference design as referenced in the schematic and test report of PMP40285 available from here (https://www.ti.com/tool/PMP40285#design-products).
The reference schematic is following and I use this part to test that LM73606 model works properly, so I can use it in a different design.
My schematic in PSPICE for TI is as follows:
And the results at VCC / VBUS1 / IL1 are following (transient simulation is set to 10 ms with maximum time step of 1 us, without any additional adjustments). The model used in simulation (SNVMBE5.ZIP) is downloaded from TI webpage (www.ti.com/.../LM73606
With skipped initial transient bias point calculation:
However, none of those achieved results lead to the desired, expected results. If I use the the build-in component in PSPICE for TI named 
, which should be an equivalent component, I got the same results. Nevertheless, I have noticed that the results further differ, if I open and use (copy) the component from model test circuit, which is available from PSPICE under LM73606RNP_TRANS transient model. The obtained results are:
There is a large difference in the output voltage from the component, while still it does not work as expected. I can share my design files via e-mail, but I got stuck at this point.
Many thanks for any suggestions.
Kind regards,
Petr Kadera
