UCC28780EVM-002: Simulation (Spice model of UCC28780 and UCC24612)

Part Number: UCC28780EVM-002
Other Parts Discussed in Thread: UCC28780, UCC24612,

Dear Sir

I would like to make a transient simulation of the UCC28780 Active Clamp Flyback 45W AC/DC EVM with GaN FET. I see that only Simplis Model of the UCC28780 and UCC24612 are available.

Could you provide the spice model of the UCC28780 and UCC24612 in order to make a LTSPice Simulation or the only way is to do a simulation using Simplis?

Thanks

Best regards,

Nicola

We only have a SIMPLIS model available for UCC28780. There is no spice model.

UCC28780 is very complicated, which will make it a challenge to simulate in spice. As a result we have released a model in SIMPLIS, which is a simulation tool that is optimized for switched mode power supply design.

Eric

Dear Eric,

thank you for your response!

Could you provide the PCB layout file of the UCC28780EVM-002 for reference (like CAD file)?

I'd like to refer the layout and try to realize the PCB by myself in order to practise.

Thanks

Best regards

Nicola

UCC28780EVM-002 was developed in Altium. Attached are the Altium files and gerber files for this design.

Dear Eric,

I'm able to open the schematic files from the design files but not the PCB project.

I'm using Altium 2018.

Please let me know

Best regards

Nicola

I am able to open the Altium project file HVP002.PrjPcb, then thru it open the schematic HVP002A_p1.SchDoc, HVP002A_p2.SchDoc and HVP002A_Hardware.SchDoc and PCB file HVP002A.PcbDoc. I have Altium 18.1.9 on my computer.

Can you let me know what error you are seeing?

Best Regards,
Eric
