TPS57060-Q1: What is the internal slope compensation for this IC?

Part Number: TPS57060-Q1


I'm modeling this IC in SIMPLIS and LTspice and I need the value ( or expression) for the internal slope compensation (Se). The datasheet presents a model that ignores it,  but I would love to know what it's so I can develop a more accurate model.  Additionally,  the datasheet says the current sensing is done on the high side MOSFET. Does it use the Rds(ON) of the FET as the sense resistor? 

Thank you

  • Hello,

    You are requesting proprietary information which I am not allowed to share.

    I recommend you either use the textbook recommendations for slope comp, or, use the SPICE model available in TI SPICE.

    The current sense in most PCM bucks I work on use the RDS of the high side FET.
