Q: What output voltage is provided by the TSDMRX-5W-EVM system?
A: 5 volts, at up to 5 watts total power. The TSDMRX-9V/15W-EVM would provide up to 15W at 9V.
Q: What mode does the TSDMRX-5W-EVM operate in?
A: Qi is the default. With PMA-3 and PMA-8 transmitter types, PMA mode is selected.
Q: Where can I find more information on the Qi and PMA standards?
A: There are a number of websites that address this subject. A good starting point for Qi would be:
http://www.wirelesspowerconsortium.com/technology/how-it-works.html.
PMA, which is now joined with A4WP, is now called AirFuel. Information on them can be found at the
following website: http://www.airfuel.org/technologies/inductive.
Q: Does the EVM part number represent something in particular?
A: Yes. The part number is broken into a prefix, main body, and suffix, separated by dashes. The prefix is
comprised of three two letter groupings that each help define the product represented. As such, the part
number can be read as follows:
Prefix characters:
1+2 = Company :
3+4 = Environment :
5+6 = Type :
Mid-section = Device Voltage and/or Wattage.
Suffix = Equipment type:
EVM = Evaluation Module
MOD = Production Module
Therefore, the TSDMRX–5W–EVM is a Dual Mode, 5 Watt Receiver Evaluation Module provided by
Semtech.
