A group of developers in Elektor Labs have modified a high power wireless power transfer project, which originally developed by Würth Elektronik eiSos GmbH & Co. KG, an electronic and electromechanical components manufacturer in Europe, in an attempt to come up with an...

Andy Brown wrote a detailed article on reverse engineering a CPU voltage regulator: A recent ebay fishing expedition yielded an interesting little part for the very reasonable sum of about five pounds. It’s a voltage regulator module from a Dell PowerEdge 6650 Xeon server. I...

This is a very simple mains isolated dimmer with a triac output (phase control). It uses timer0 to do the timing. There is no user interface, the value of the triac ignition delay after a zero crossing is defined by setting the reload value of timer0 (Tmr0) in the software...

Abdulgafur tipped us with his latest project, a 5V solar powered power bank. The circuit consists of two stages, the first stage is the battery charger stage based on MCP73831 and the second stage is the step up converter based on LT1302-5 which converts the battery voltage to...

A new type of batteries called “Printable Solid-State (PRISS) Lithium-Ion Batteries” was designed by a group of researchers from the Ulsan National Institute of Science and Technology (UNIST, South Korea). The new battery is created from consecutive layers of printed composite...

Intersil published a new white paper titled “Preventing Subsystem Brownouts in Mobile Devices“. This white paper demonstrates the benefit of using a buck-boost converter as a pre-regulator, which leads to better overall system efficiency and enhanced battery life. Systems...

If your application requires a changing supply voltage, then this new IC is ideal for you. Intersil announced the ISL91128, a new buck-boost regulator. The new regulator has an I2C interface to select a broad set of features including output voltage range and slew rate. This eliminates...

If you have a single Li-Ion battery powered application, then you need to think about using AS1383 in your design. AS1383 is a DC-DC boost converter comes in a 6-pin WL-CSP package with 0.4mm pitch, a very small package suits the limited space applications. In the below image, you can...
