How to shrink your USB Type-C battery charger [PDF]
https://www.electronics-lab.com/shrink-usb-type-c-battery-charger-pdf/
Maxim’s app note on a highly compact Type-C charger solution. A highly integrated solution, as seen with the MAX77860 USB Type-C 3A switch-mode charger, dramatically reduces system complexity by integrating the charger, the power path, the Safeout LDO, ADC, and the USB-C CC and BC 1.2 detection in a small 3.9mm x 4.0mm, 0.4mm pitch, […]
Oscilloscope Differential Probe USB Power Supply
https://www.electronics-lab.com/oscilloscope-differential-probe-usb-power-supply/
By Dr. Martin Oppermann (Germany) & www.elektormagazine.com 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 […]
