Switching Adaptor
Adjustable Switching Adaptor Circuit This is an easy way to create an adjustable switching adaptor power supply that uses a monolithic L4970A Switching Regulator IC DC-DC converter family. By using a negative reference voltage equal to the value 5.1 device, then this is a classical solution with high performance. Negative reference voltage is raised another secondary winding of the mains [...]
24V to 12V Converter
24V to 12V Converter Circuit Here is a 24v to 12v converter. Why do I say so? From experience to find the circuit schematic “24V to 12V converter“, the internet search results always show the opposite, namely “12V to 24V Converter”. Or even the title of the article “24v to 12v”, but the contents of the article describe the reverse. [...]
High Voltage DC DC Converter
High Voltage DC DC Converter Circuit This high voltage DC DC Converter is a regulated high voltage power supply used for Geiger Muller tube variant of the cosmic ray muon detector. Input voltage from high voltage DC DC converter is 12V AC at 800mA current and then converted to DC through a bridge rectifier Diode 1A. The voltage output of [...]
9V Adapter
Build an Uninterruptible 9V Adapter This 9V adapter circuit can be built with low cost and function as an uninterruptible power supply because it comes with an external 12V battery backup. A simple DC power supply 12V unstabilized used as a source of supply. The 9v adapter output voltage of this should be in stable condition, the input voltage to [...]
DC to DC Converter Circuit
High Efficiency DC to DC Converter Circuit DC to DC converter circuit is a circuit that receives a DC input voltage and generates a DC output voltage. DC to DC converter is very necessary in a portable electronic device that is operated primarily by batteries such as cell phones and laptop computers. These portable electronic devices often contain several sub-circuits, [...]
