TPS562201: How to calculate the current limit in different components design?

Part Number: TPS562201

Dear experts,

I would like to know how to calculate the current limit of TPS562201 with different output inductor.

Per my understand, it have based on the current waveform in phase node.

So current limit will be different with different Vin, Vout and inductor.

Thanks!

    hi Ben,
    Yes, your understanding is correct. there is a little difference under difference VIN, VOUT and INDUCTOR.
    The device has fixed OC threshold, but also has response time afer detect the OC. So the test value in phase mode show a little difference. Main influence factor is slew rate of the inductor current droop.
