Já vou avisando que este dispositivo apresentado aqui é dimensionado para pequenos circuitos eletrônicos, in other words, circuits that do not require too much current for its operation.
This circuit as above may be fed with voltages 1,5 Volt a 5 Volts, which can be obtained by batteries or battery 1.2 Volts ou de 1.5 Volts.
Conversor CC/CC de 5 Volts to 12 Volts
This DC / DC converter also uses the integrated circuit LT1073, only version “-12” ie the LT1073-12, which has its stabilized output 12 Volts, since the previous LT1073-5 has its stabilized output 5 Volts.
As we have seen the converter heart is the LT1073 is a DC / DC Converter Chip Linear Technology. Since the diode can be used any fast diode. The output current is 100mA with a maximum input voltage 4.5 Volts.
You can also Article Voltage converter DC / DC 1.5 Volt para 3 Volts that does not use integrated circuits and transistors yes.
