Other Parts Discussed in Thread: TPL5111

Dear everyone,

I want to generate periodic pulse signals for reducing power consumption.

So I am looking into the TPL5111 for this purpose.

Also, I want it to generate the signal by itself. I mean I don't want to use DONE pin.

Is it possible to use this IC with grounding DONE port? 

Here's my final goal;

    The answer by myself.

    It works well as I expected. I have tested with its EVM board.

    Without DONE signal, It generates the periodic DRVn.

    Only I need to complain is that I have confused due to the manual.

    There's a timing chart on Page9 Figure8 Where I can see Forced DRVn falling looking like sustaining at low-level continuously. 

    I guess it should be 50mS pulse signal.

    Thanks,
