Nexperia has introduced its first 5V load switch IC, which operates across 2.5 – 5.5V with 110mA to 2.5A current limiting. The 2 x 2mm NPS4053, as it will be know, is optimised use in portable devices ...
There are several ways to produce a negative voltage from a positive voltage source, including using a transformer or two inductors and/or multiple switches. However, none are as easy as using the ...
My understanding, all USB ports provide 5v. I am trying to get voltage from TV USB port to power an input switch relay box (would turn on when TV turns on from standby and starts powering the USB ...
