FAQ:

Q: How to convert 12V to 9V using DC to DC converter?

A: These DC to DC converter circuits can be used to convert all types of 12V supply to 9V supply. These circuits can also be used to step down or reduce 12v battery potential to 9v so as to use it with microcontroller modules or any IC’s. Here we mainly use reliable linear power converters like LM7809 and LM317.

Q: Can I use a 12V adapter with a 9V pedal?

A: Some pedals like the Fulltone OCD are rated from 9v to all the way up to 18V which in this case, yes you can use a 12v this adapter because the pedal is capable of handling that much voltage. Giving a pedal more voltage to play with (18v instead of 9v) will typically provide a larger range of headroom before the guitar’s signal starts to clip.

Q: What is the best linear power converter for 12V to 9V?

A: Here we mainly use reliable linear power converters like LM7809 and LM317. LM7809 is a fixed voltage regulator IC that reduces and regulates the input voltage in electrical circuits. A voltage regulator 12v to 9v converter with IC LM7809 is implemented as shown in the schematic diagram below.
