Other Parts Discussed in Thread: TPS53355,
Tool/software: WEBENCH® Design Tools
I have created several designs in WEBENCH with the TPS53353 and TPS53355 from a 5V input. If I run the Sim Tool (Start up or steady state) I get unstable waveforms for every condition I have entered. Output voltages I have tried are 0.74Vout, 0.75Vout. 1.0Vout, 1.2Vout, 3.3Vout. Currents have ranged from 10 - 15A and ambient is set to 30C. Can you confirm this is an issue with the model? Or are the values calculated by the design tools truly unstable?
Similar conditions with 12Vin seem to work fine.
Thanks!
