TPS26600-02EVM: Set up IMON resistor

Part Number: TPS26600-02EVM

Hi team,

Customer use our calculation tool to calculate IMON resistor.

But the calculation result is different from the datasheet.

If l(LIM) is 1A， so R(IMON) is 33.3k, right?

I suggest him follow the datasheet first.

Many Thanks,

Jimmy

    Hi Jimmy,

    78.28 μA/A is the typical current monitor gain as per EC table.

    Suggest to follow equation (14) and use 78.28 μA/A instead of 75 μA/A for the calculations. For 1A current limit, we get R(IMON) as 31.93k

    Best Regards, Rakesh
