LT3752-1 PWM controller IC ..How to calculate blanking resistor value?

[treez]

Hello,
The equation at top left of oage 28 of the LT3752-1 datasheet gives an equation for the blanking time. However, it has a parameter "k" in it.
Do you know what is this parameter "k"?

The datasheet does not explain.

Not a parameter, just a sloppy way to write design equations.

Means factor 1000 respectively resistance in kohm. If the equation is too confusing for you, read the graph on page 12.
