A. Block Diagram
The TSWIRX-LI-EVM may be divided into a number of sub-blocks as show in the diagram below:
Antenna: Transmit – primary coil providing power to the receiver; part of TSWITX-G2- EVM
Antenna: Receive – secondary coil in the flux field of the transmit antenna; part of the 1 MHz resonant
tank
Rectifier – converts AC voltage from the antenna to positive values; FET based for high efficiency
conversion
Regulator - based on the TS51223; converts rectified input to regulated 5v output; includes protection
circuitry
Comm. Generator - produces the 'handshake' signal telling the transmitter to provide power
Comm. Modulator –– sends the handshake signal to the transmitter
Battery/Load – end equipment to be powered by the wireless receiver
