TPS659037: SMPS maximum current limitation

Part Number: TPS659037

Hello support team.

I'm considering the peak current of inductor.

However, I can't find the current maximum limitation of SMPS in datasheet.

Should I think of it as IOmax?

Best regards.

    Hello,

    Are you looking for the steady state DC maximum output current for each SMPS rail? Those values are found on the third page of the datasheet and I have included these values below.

    SMPS1_2_3: 9A

    SMPS1_2 dual phase: 6A

    SMPS3: 3A

    SMPS4_5_7: 6A

    SMPS4_5 dual phase: 4A

    SMPS6: 2A or 3A (based on OTP programming, see datasheet for details)

    SMPS7: 2A

    SMPS8: 1A

    SMPS9: 1A

    Specific current limits for the high side and low side FETs can be found in the electrical characteristics table of the datasheet.

    Best regards,
