# DC to DC Converter Circuit Diagram

DC to DC Converter Circuit Diagram
In some applications, one needs a voltage level that is higher than the one immediately available, like in programming EPROMS: a 25V is necessary, but common digital circuits have only 5V and 12V lines.
This converter circuit solves that problem. It converts a DC voltage to a much higher level. To be able to obtain the desired output level, use Table 5.1 to know the correct value of Rx.
