PTH08T210W sense input resistance

James Long

The datasheet for the PTH08T210 module has a section on page 21 about the remote sense inputs. 

It says that the sense pins have internal low-value resistor connections to the respective output nodes. 

Whilst this gives a number of 15ohm or less, I can't find any more data on the actual range of values that this could take.

 

Could you give a min/typ/max value for these resistors?

 

The reason is that I am using this module in a design where the remote sense is connected to the special voltage sense pins of a large processor and I think that there may be too much resistsance in this connection to make the sense useful. the processor vendor says that the voltage sense pins are connected to the processor's core power supply, but they also do not quantify the range of resistance I should expect to see.

 

Thanks

James

    The remote sense resistor value is 10 Ω +/-1% . The remote sense pins must be connected directly to their respective buses. There must be no other component, resistance , inductance , diode or  semiconductor connection between the remote sense pins  and module vout pins.
