TPS50601-SP: TPS50601-SP Worst Case Model

Part Number: TPS50601-SP
Other Parts Discussed in Thread: TPS50601A-SP,

Hello,

I am using the TPS50601-SP AVG TINA model to find the phase and gain margin but I am unable to measure the gain margin. I found a TPS50601A-SP Worst Case Analysis Unencrypted model in which I was able to simulate and measure the gain margin. Using the same circuit, I tried the same measurement with the regular TPS50601A-SP model and was unable to measure the gain margin. I am assuming I need a worst case analysis model for the TPS50601-SP in order to measure the gain margin.

 I'm not sure if the TPS50601-SP has a worst case model, but if so is it available?

Thanks in advance!

    Hi Robert,

    Could you share your simulation files or at least screenshots of your schematic and measurement results so I can see how you have it set up? Both the Average and WCA models are capable of providing full frequency response results. 

    Regarding the question about the TPS50601-SP, there is not a WCA model for this device. 

    Thanks,

    Sarah
