Simple 12V to 9, 7.5 or 6V converter

simple DC to DC ConverterYou’re traveling and you forgot to bring DC to DC converter in your car, but you need it. This simple DC to DC converter circuit can help you.

This DC to DC converter circuit enables transistorized items such as radio, cassettes, and other electrical devices to be operated from a car’s electrical supply. The table gives values for resistors and specified diode types for different voltage. Should more than one voltage be required a switching arrangement could be incorporated. For high currents, the transistor should be mounted on a heatsink.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
