Hello.
Do you have power up simPE model of ADP1853?
ADP1853 simPower don't have export menu of start-up
And I tried to make start-up model using the export SimPower model, but didn't go well.
I want to know soft-start and Pre-charge simulation.
best regard.
Hello.
Thank you for your sim data.
Immediately, I tried the simulation.
My customer's request current is 2A~10A, it changed the load.
The result is an attached graph.
However, because at light load there was ringing. I tried to optimization.
My customer request is Vin=12V~3.3V Vout=1.2V,Iout=2A~10A.
I tried to optimize in this condition.
Finally, I introduced the circuit conditions from ADIsimPow.
Ringing was suppressed by the phase compensation of the entire circuit.
Soft-start was a result of similar calculation values.
But I have a question, that Why flat Voltage output appears, is it dependent on the input voltage ?
Best Regards,
