OSCILLOSCOPE DIFFERENTIAL PROBE USB POWER SUPPLY

An ultra-simple power solution using USB In his article published in the July & August 2016 issue, Elektor author Alfred Rosenkränzer presented a wonderfully simple differential probe for oscilloscopes, based around the AD8479 precision differential amplifier. I built one of them immediately and found it particularly suitable for measurements in the audio range, for example. But one […]

USB CHARGING PORT CONTROLLER USING TPS2514

Texas Instrument’s USB Dedicated Charging Port Controller TPS2514 is specifically designed to implement the charging schemas mentioned below. An auto-detect feature monitors USB data line voltage and automatically provides the correct electrical signatures on D+ and D– data lines. Note that the chip datasheet never mentioned Samsung or Apple in particular apparently due to the copyright issues.

8 GHZ SAMPLING OSCILLOSCOPE FOR EXPERIMENTS

A basic open-source multi-GHz sampling oscilloscope for experimenters on a budget. Still a work-in-progress, with key pieces on separate PCBs, but showing bandwidths in the 7-8 GHz range with >= 100 GSa/s equivalent-time sampling, and around 500 k comparisons/second real time. So far. This project is the culmination of some of the experiments over on #The

ISOLATED 2W 24VDC-TO-5VDC FLYBACK DC-DC – REFERENCE DESIGN

The MAXREFDES111# reference design from Maxim Integrated is a compact 24V input flyback-converter module that features 5V at 400mA output. Transformer selection is often the most difficult step in isolated power design. Multiple transformers (Wurth Electronics 750315847, HanRun HR041087, and Sumida 06343-T588) have been qualified for this design, simplifying the process of transformer selection. The reference design delivers a
