TPS25982: The question about the graph of the TPS25982 datasheet.

Part Number: TPS25982

Hi team,

For the TPS25982,  for the yellow part, it may have some misunderstand. The Vout is pulled down by the load side. If not pulled down the load, the voltage drop between the Vin and Vout will be only Ilimit*Rdson. But so large as the yellow part. Thanks.

    Hi Xiao ,

    In current limit mode, the output voltage is decided by the load impedance and the current limit value.

    The device regulates to the set current limit (ilim)  and forces that through the load.  Vout= ilim*Rload. Where Rload is the load impedance.

    Best regards, Rakesh
