Use the SS input to limit input current

Question asked by KurtBecker on May 7, 2018

I want to use the LT3958 boost converter

24V input and 70V output.

Most important, the input current shall never exceed 1A at 24V, even when this means reducing the voltage at the output.

Can I use the SS (SoftStart) input to do that?

I have used LTSpice and put a voltage divider from INTVcc to GND, center to SS (10K, 1K) and it seems to simulate ok.

Before I make a PCB... does anybody has an idea why this may not work, or even has a better idea.
