TPS7H5001-SP: Active control of PS and SP pins

Part Number: TPS7H5001-SP

Tool/software:

I've been trying to tune a power converter design for good efficiency at both heavy and light loads, and one thing that stands out as being potentially very helpful would be the ability to electronically tune T_ps and/or T_sp based on the loading conditions of the converter. In other words, I'd very much like to be able to drive the PS and/or SP pins to set a desired dead time based on sensed parameters of the circuit, but I wanted to reach out to see if I could get a better sense of how best to do that (i.e. would a stiff voltage source to force a given voltage at those pins be best, a constant current source, something different)

  • Hey Brian,

    The PS/SP pins are current mirrors internally that aren't the most responsive to changes.
    I would worry that it could be multiple cycles if not more that the dead time would not adapt to external stimulus.
    While this is something you could try, this configuration is not something we have tested.

    Thanks,
    Daniel
