Sony Wii charger_ Y2009
 Designed for Ni-MH battery charging
 Data code for transmitting charging status
and switch power on/off.
 Wii Charger sales to the United States in 2009
 No power adjustment and coil offset correction
 Available power below 1W
FDT on Y2012
40W
 Output power up to 80W
 Designed for DC power output
 Power automatically adjust
 Coil offset correction
 Transmission data affect few pulse of
resonance wave
 Simplify circuit the same as the
previous generation
 Efficiency up to 80%
 Standby current less than 1mA
80W
 Enhance response to prevent high voltage
to damage RX board
(freq = 20 1/sec, modulation time = 1uS)
 Strengthen the anti-noise processing
capabilities
 Wide range of input voltage
 Solve the problem of coil noise
