This is a ADP1821 Step Down DC-to-DC Converter circuit. This circuit uses ADP1821 that is synchronous pulse-width-modulated (PWM), step-down controller, inexpensive and versatile. It can drive all N-channel power stage to regulate an o…
This circuit shows a doubler voltage with ne555 schematic. This will be Simple Doubler Voltage circuit, from voltage 12VDC to be 24VDC. By use Timer IC highly popular the number NE555 and other equipment a little again. It can give current get ab…
This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V (British?) car. The circuit is simple, about 75% efficient and quite useful. By changing just a few compone…
This schematic shows you how to build a dc-dc schematic.Here's a DC to DC circuit put together just from parts found on the test-bench. All it took was two transistors, two resistors, an audio transformer, a bridge and two caps. It may no…
The laptop adaptor described here plugs into a car cigarette lighter socket and produces a 19V nominal output voltage adjustable by + - 0.5V. The input voltage range is from 9.2V to 15V and the output voltage shows good regulation even with larg…
