    Are you sure you want to build it? They're very inexpensive.

    Hi Sachin

    I would make it simple -> Simple Switcher

    I cannot promise 100% that the suggested circuit will work, because I did not test it.

    I just changed an existing Inverting Buck−Boost Regulator with LM2575-12 from the LM2575 data sheet, to the adjustable type LM2575-ADJ (LM2576-ADJ would also be ok), that has input voltage 5V included.

    Would be interesting to hear from somebody who has time to test this circuit (I never saw it before)!
