Hi,
I need to limit the voltage output of an LM2596 from 7v to 14V. According to the datasheet if R1 is 1k than I can put R2 as 4k7 to get ~7V and 10k3 for ~14V
Question 1: As per my attached schematic - this is how I solved it - is it correct? would you have clamped the resistance differently?
When the input voltage is not high enough, it is understandable that the regulator will drop some voltage and output whatever it has "available".
Question 2: Is this how it would work? I don't understand this bit.
Thanks all
