TPS610981: Purpose of SS parameter in unencrypted model

Vasyl Vorobei

Part Number: TPS610981

Hi! I'm trying to simulate a simple circuit with a TPS610981 converter, and I'm wondering about the purpose of the SS parameter in its model. From model itself I see that it's some initial condition stuff (possibly startup/steady mode selector?), but not sure how to use it properly.

Hi Vasyl:

The SS parameter is to reduce the simulation time during our debug. It can start the simulation without startup process in proper initial status (like Cout initial value). But it needs some experience to use it properly.

It's OK if you set it=0 and ignore it.

So basically I've got it right - I can run the simulation with SS=0 if I need a startup response, or set SS=1 with defined initial conditions for steady mode/transients simulation. Thanks
