LM5069: Discrepancy Between Power Limit Calculation in Datasheet and Calculation Tool

Part Number: LM5069

Hello,

I am going through the design process for the LM5069, following the datasheet and also using the calculation tool provided for the IC.  I'm finding a discrepancy between how the power limit is calculated in the datasheet (Eq 9) and the value I am getting from the calculator tool.

For a desired power limit of 450W, with Rsns = 0.67 mOhm and Vds = 60V, I get a required resistor value of 30k.  But in the design calculator tool I have to put a resistor value of 37.5k to get a 450W power . limit.  Which is correct?

Thanks and best regards,

Jessica
