  • I am interested on this "USB 5V/3.3V" power supply. It can be convenient in some situation. But I am wondering if this circuit can reach its announcement, a 500mA max current? According to the specification, a USB 2.0 port, when in the unconnected status, can only supply 100mA max current, before the device requests for more. I check its schematic and the D-/D+ pins are left open, which means that there will be no device appears to the USB port. This power supply seems can only supply a 100mA max current. Am I worng?

No public wish lists :(
