Re: Low voltage supply spike protection?

Hi Alan, I am making the converter, so no problem re the positive earth. If I use a ready made module I might have a problem. I intend using a SMD voltage regulator to reduce the 12-14volts to 3v. with the PCB mounted inside the radio case I may be able to make use of the inbuilt protection. John. |
