Hi,
I'm considering the LTC1871.
I'm considering using it with an output voltage of 36V or higher.
In this case, I think it will be designed like the circuit with VSW > 36V in Figure.2.
How to set the resistance value of Rs?
Best regards
Yuya

Hi Yuya,
Please refer to the page 15 of the LTC1871-7 datasheet to be able to calculate the value of the Sense Resistor.
