    DC power supply circuit for +9V -9V and +12V what is needed are 2 power supplies both switch mode and they must both be regulated I have looked at using IC's 7809, 7909, 7812 but they are inefficient the Power supply in is 4X 3.7V 3000mamp lithium ion cells =14.8V

    The 78xx and 79xx are NOT switching type regulators, they are linear.

    How much electronic design/electronics assembly experience do you have? This isn't going to be a small project.

    Hmm I am not electronics trained or work in this field but it was easy to find out how from a Google search the Data sheet for a LM2595 1A or LM 2596 3A shows it all both for + and - supply A very simple circuit.

    Instead of focusing on the parts, what do you need for a supply, voltages and current?

    What are your input options for this supply?

    We will work from there to get the simplest yet useful Power Supply that fits your needs.
