12V to 24V DC Converter Circuit
The circuit which we have explained below is used to generate the output voltage whose magnitude is just double of the supplied input voltage. In our circuit, we have supplied 12 volt in the input terminal and receives 24 volts approximately at the output terminal. The basic building block of the circuit made around a very well known IC CD4049 which is a hex inverter. This can be constructed, with the support of single IC along with some other components.
As shown in the above figure, CD4049 holds six inverter gates on a single package. In this IC, for input purpose pin 3 is used while for the output purpose, pin 2 is used for the first gate. In the same way for the second gate, pin 5 is used as input and pin 4 as an output terminal and in the same manner for rest all the gates. For the supply voltage pin 1 is used and for the ground purpose pin 8 is used. While pin number 13 and 16 are not used. The IC works on the voltage range from 3V to 15V excessive voltage more than 15V will destroy the IC. So provide input voltage in the range of 3V to 15V.
