Voltage Doubler from 6VDC to 12VDC

Voltage Doubler from 6VDC to 12VDC
This is the circuit diagram of voltage doubler, or it can be called DC to DC converter circuit, from 6 Volt DC become 12V DC. This dc voltage doubler circuit will need about 2A from the 6V input supply to produce the full 800mA at 12V for the power output. (more…)

24v to 12v converter

24v to 12v converter
As shown, the 24v to 12v converter circuit is nothing more than an integrated adjustable voltage regulator that acts on a group of power transistors in parallel. These transistors can be said to perform heavy duty while the regulator responsible for controlling them. (more…)

12v to 24v converter

12v to 24v converter
Is often you need to install some equipment in a car that works with the 24 volt source. May not be a problem for buses or trucks which have the power to work with two batteries in series. But the cars have only one battery, so it becomes necessary to raise the voltage electronically. (more…)

Symmetric 12V to 5V converter

Symmetric 12V to 5V converter
With this simple DC voltage converter circuit we can reduce 12v to 5v  symmetric voltage and can use existing resources. Here used 3-Terminal Adjustable Regulator LM317  for positive regulation and LM337 for the negative regulation. The maximum output current is 1A, and as always highly recommend a good heat dissipation for this IC regulator. (more…)

Converter 3v to 5v

Converter 3v to 5v
We see that almost all of which are available today in addition to the microcontroller powered by a battery. But if we do not want a 5V in many cells in series ... You can use the Converter 3v to 5v circuit described here. (more…)

Car DC to DC Converter for laptops

Car DC to DC Converter for laptops
Laptops today are the what is called notebook computers, which now is becoming popular. Laptops can be brought into the bag making it suitable for business trips. And even as the "home entertainment center" laptop is more convenient, because it takes a little space. However, in my opinion, there is one very important which become shortcomings - most laptops which powered by an electric voltage of 19V, making it impossible for them to direct the power to an integrated

Bipolar +/- 15V and 5V from Car Battery supply

Bipolar +/- 15V and 5V from Car Battery supply
This DC to DC Converter use Max 541 from Maxim, IC1 is a switching regulator that generates a 45-kHz signal that drives the gate of MOSFET Q1 BUZ71A from Motorolla. The source of this power supply comes from a 12V car battery voltage. This DC to DC converter have an output  +-15V and 5V. (more…)
