Simple 12V to 6V converter circuit

You're out and about and you forgot to bring a DC-DC converter in your car, but you need it. This simple DC to DC converter circuit can help you.

This DC-DC converter circuit enables transistor-based items such as radios, audio tapes, and other electrical equipment to operate from a car's power supply. The table below gives the different voltage values ​​of resistors and specified diode types. Multiple voltage switching arrangements can be incorporated if required. For high currents, the transistor should be mounted on a heat sink.
