The output voltage of a supply can be increased by “jacking up” the voltage produced by the 7805. The way the 7805 works is this: It maintains a voltage of 5v between output and common terminal. If the voltage on the common terminal is increased (jacked up), the output voltage will be 5v higher. The [...]

In conventional applications, switching-regulator ICs regulate VOUT by controlling the current through an external inductor. The IC in Figure 1, however, driving a diode-capacitor network in place of the inductor, offers comparable performance for small loads. Made of readily available components, the network can double, tripple or quadruple the input voltage. Though somewhat less efficient [...]

Every electronic gadget primarily needs a D.C, power supply to energise it. It also forms the basic requirement for any constructional project. consequently there is a need to obtain multiple voltage values for cost reduction, convenience and compact arrangement for all the above applications.
The required D.C. power supply is usually obtained by means of a [...]
