This simple converter uses a zener diode and a transistor to convert 12V dc from a battery to 6V DC with a maximum current of 1A. The circuit is very easy to construct and requires only 3 electronic parts, the resistor, Zener diode and transistor. The transistors is TIP41C, zener diode is 1N4733A or any zener with the same voltage drop and power. Resistor is 6ohm 6W and preferably wire-wound type. This is useful in powering devices that uses 6V DC such as radios.
The output voltage is given by the formula :
Vout = Zener voltage + 0.65V , where 0.65V is the base-emitter voltage of the transistor
