TPS7A8300: Why Can't I perform WEBENCH on the TPS7A8300 with VIN = 4.5-5.5 and Vout = 1.8V?

Part Number: TPS7A8300

WEBENCH is unable to open a TPS7A8300 design based on the following parameters:

Vin = 4.75V min, 5.25V max

Vout = 1.8V

  • Hi Kerry,

    Did you leave the current at 2A? It would not work when I left it at 2A but I reduced it to 0.1A and it ran. I'm guessing it has thermal metrics built into it because 5V to 1.8V at 2A is over 6W.

    Regards,

    Nick
