TPS54233 in SwitcherPro - Gain Margin 'stuck'

Other Parts Discussed in Thread: TPS54233

I have been playing around with the TPS54233 in SwitcherPro and have noticed that no matter what I do with the compensation R's and C's, that the Gain Margin is stuck at -1dB (never changes). What's up with this?

    Hello Mark,

    We tried some designs with TPS54233 and we got different gain margin. Can you please post your inputs and R and C values you used?  

    Thanks,

    Hi - I already deleted the design & attempted to start a new one... but SwitcherPro failed to generate a design- saying that it could not find any capacitors for the design.

    So I tried another IC & it worked fine... then tried the TPS54233 again - same result. Something doesn't make sense to me.  Please let me know.

    Hello Mark,

    If your design got halted due to no capacitors found, then that may be right. We have limited number of passive parts in our database. Eventhough we have added many passive components in last few months, we stil cannot cover every input range for all ICs.

    We are working on a feature 'user-defined parts' where the user wil lbe able to add their own parts in our database. That way, if a design gets halted due to lack of a specific part in our passive parts library, you can add that specific part yourself. This feature will be available in our future version v4.0 around October-November timeframe. 

    Thanks,
