Wireless power module introduce

Content

• Application of FDT solution

• Operation introduce

• Patent

• Complete security code

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 Y201240W

80W

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 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
