Hi there, im now facing one problem which i need to doubling my output voltage to 10vDC -15vDC. As we know, the voltage from microcontroller only 5vDC. Is there any circuit or component i can use to doubled my output voltage. I have try one circuit which i will upload later. When simulate in multisim, everything seem function but when i transfer it to real circuit, it didnt function as expected more worst the output voltage decrease to half of the input. Anyone can help me?
