Why Does My IC 7660 Output Match the Input Voltage?

[parames]

hi,everyone
i used ic 7660 to generate 12 VDC by using solar panel...when i used,why do i get the same output just like if the input voltage is 5V,the output will become 5 V too.

Hi there
welcome to PF :)

how about showing us the circuit you used and that way we may be able to see where you may have gone wrong. That chip may not be suitable for what you are trying to achieve

edit ... you should have not made a new thread for this rather you should have posted in the same thread that you already started on this topic

cheers
