WEBENCH® Tools/TPS5410: TPS5410 Average model issue related to CCM and DCM

Part Number: TPS5410

Tool/software: WEBENCH® Design Tools

Hello,

I have downloaded TPS5410 un-encrypted average model from TI website & ran the un-encrypted model in OrCad PSpice 16.6.
Does this model work in CCM only or it auto-toggles between CCM & DCM.

Look like model works only in CCM. Please clarify.I have attached waveforms related for your reference.

1.Vin=12v Vout=5v Rload=5ohm Fsw=500KHz waveform 1

2.Vin=12v Vout=5v Rload=50ohm Fsw=500KHz waveform 2

Hi,

Yes the model works only in CCM.

I wanted to check the stability in DCM mode,can I modify the external circuit and make it work in DCM mode.

Hi,

We don't have model that support the loop response simulation in DCM.

The DCM loop is fine and always stable, don't worry about that.

please send email to me neal-zhang@ti.com if you have further questions.
