WEBENCH® Tools/LM2733: [LM2733XMF/NOPB] Webench simulation output is incorrect

Valentin P.

Part Number: LM2733

Tool/software: WEBENCH® Design Tools

When using Webench power designed to design a power supply, the simulation output is incorrect.
Part: LM2733XMF/NOPB
Vin: 4.5-5.5V
Vout: 19V
Iout: 0.1A
Temp: 30°C

The simulation is not working properly, output voltage is totally incrorrect (<5V, instead of 19V) - see attachement

Hi Valentin,

We are able to replicate the issue.We are looking into issue of why the output voltage is settled to lower value. We shall keep you updated on the same.

Thanks and Regards,
