- Basic DC-DC Converter -

Here you can find a very simple circuit for powering your projects based on Intergrated Circuits (like I/O Interface ecc..).

                                                - Circuit Schematic -

All is based on the LM78xx IC, with the same schematic you can build different voltages, you had only to choose the appropriate IC, for example, if you want +5 Volts, you must use the LM7805 , for 12V the LM7812.

This is the circuits :

This is what you need :

- 1 Diode Bridge
- 1 Electrolityc Capacitor 47uF (C1)
- 1 Capacitor 0.01 uF (C2)

- 1 LM7805 Voltage Regulator
