LM2676S-ADJEVM: Bode plot on webench doesn't work

?? ??

Part Number: LM2676S-ADJEVM

We need to compare with new regulator design and old design of LM2676S-ADJVM.

Webench(bode plot) doesn't work for LM2676S-ADJVM(5V fixed output) model with standard optimized parameter.

If it has some setting for work, please let us know.

There is no setting for this to work.

Just ensure to follow the inductor and capacitor recommendation in the datasheet.

Thank you.

Sorry for my mis-discribe.

Correctly it need to change to LM2676SX-5.0 from LM2676S-ADJVM.

You can use LM2676S-ADJVM. and set the Vout to 5V and get the bode plot.

Thank you.

Does LM2676SX-5.0 and LM2676S-ADJVM(5V setting) has same frequency response?

Can it be guranteed?

We have to use LM2676SX-5.0.

Yes, the frequency response should be same when you configure the ADJ version to 5V output.

OK, we attempt to replace to LM2676SX-5.0 from LM2676SX-5.0 without simulation.

Thank you.
