delivers up to 500 mA or 0.5A. Also, with a USB 3.0, it can provide up to 900mA or 0.9A, which translates into 4.5 watts. These power output specifications are a rating based on the 5 volts from each standard output. However, the USB 3.0 dedicated charging and c...
It's true. Another of my ideas that someone with actual talent, drive, VC money and skill with electronics has taken to market.Rechargeable AA batteries that recharge using the 5 Volts DC that every USB Port carries. Brilliant. Plug them into your laptop or any computer and...
Initial USB-C negotiation is also going to prevent damage to a device in the handshake process. During this handshake, the cable communicates back-and-forth what power should be distributed, and what combination of volts and amps should be applied from the charging device to the device that ne...
I have some basic knowledge of SMPS voltage regulation feedback circuit concepts, and basics of control systems theory, mainly conceptually. I've hacked various PSUs and 5V battery chargers to make them variable voltage supplies. I'd like to learn some more about how power supply engineers det...
