LM2576HVS-5.0/NOPB in Proteus

Hello there,

Thank you for reporting the issue. We are going to investigate this and we will get back to you soon.

Hello,

It seems that the part is importing correctly on Proteus, and it's ready to be downloaded.

The reason this part has 6 terminals is because of the KTT package this part has - The tab is included on the land pattern. Please check page 42 of the datasheet for more information:
