All,
We have the LM2596 , 12V, fixed output on our board.
LM2596SX-12/NOPB
The input to the switcher is about 24V and I was expecting to see 12V on the output. Instead I am seeing 24V.
When I reexamined the datasheet there is a circuit guideline for fixed output and adjustable output versions.
Turns out we have the fixed output in the adjustable version of the circuit. Meaning there are some other components in the feedback sections. (cap, 2 resistors).
I am thinking I will just remove these components and just short the regulated output back to pin 4 (feedback) through he pads of the removed components.
I just wanted to get some feedback from the forum to be sure I am not missing something here.
Thank you.
