5V to 12V converter circuit without transformer

5V to 12V CONVERTER CIRCUIT WITHOUT TRANSFORMER

Make 5V battery source capable of delivering 12V.

By using this circuit you can make 12Volt from a 5volt battery.

It is a very useful circuit for almost all electronics applications.

Most of the circuits that we discussed so far is powered by 12V battery source. Sometimes you may find difficult to get a 12V source, in such cases you can use this circuit with a 5V source.

This circuit is simple to construct, cheap and efficient. Ic LT 1070 is the heart of this circuit. It is a linear Technology switching regulator, commonly used for buck boost and switching applications.

The inductor L2 and capacitor C4 forms an output filter, which eliminates the excess ripple voltages from the output.

From this circuit, by an input of 5V, you will get an output of about 12V, 1A.

It is transformer less stepup voltage circuit. Due to the absence of transformer the circuit is compact and cheap.

NE566 Function Generator Circuit Diagram

The NE566 Function Generator is a Voltage-Controlled Oscillator of exceptional linearity with buf fered square wave and triangle wave outputs. The frequency of oscillation is determined by an external resistor and capacitor and the voltage applied to the control terminal. The Oscillator CAN be programmed over a ten-to-one frequency range by proper selection of an external resistance and modulated over a ten-to-one range by the control voltage, with exceptional linearity.

Transceiver Homebrew QRP SSB 80M Band

Radio communication transceiver is a radio transmitter at the same time the plane doubles as a radio receiver used for communication purposes. It consists of the transmitter and the receiver are assembled in an integrated way. In mulamula generation, the transmitter or receiver or transmitter and receiver sections are assembled separately and is part of a stand sendirisendiri and can work well sendirisendiri Currently employed both parts are integrated in turn. Aircraft simple transmitter consists of an oscillator generating radio vibration and this vibration after vibration boarded with our voice, in a technique called dimodulir radio, then by the antenna is converted into radio waves and transmitted. As we know that the sound waves we can not reach long distances, although its power is quite large, while the radio waves with a relatively small force can reach a distance of thousands of kilometers. In order for our voice can reach a far distance, then our voice superimposed on radio w...
