LM2575-ADJ negative voltage output

[stoyanoff]

Greatings! I saught this schematic in the LM2575-ADJ datasheet -
This is for LM2575-12. Is it possible to use this schematic for LM2575-ADJ with adding voltage devider on the feedback pin? Is the algorith for calculation of the devided the same?!
Thanks!

Assuming you bought the adjustable version, yes there is. Page 12 shows the calculation for doing the voltage divider to set your output. **broken link removed**

Hi stoyanoff
Of course it can be yielded by any type of LM2576 . but with some little changes . for more information refer to the datasheet and read it carefully .
