A. Block Diagram
The TSDMTX-5V2-EVM may be divided into a number of sub-blocks as show in the diagram below:
5 Volt Filters - smooths the 5 volt input supply, with QC2.0 adaptor, it will be 9V supply.
Convertor- When 9V operation, QuickCharge 2.0/3.0 and BC1.2 support, TS31023 is for 9V to VCC3V
and VCC5V.
Controller - based on the TS80000 Wireless Power Controller. Includes I/O: USB, I2C, Temp Sensor,
LED display
FET Driver - based on the TS61002 Full-bridge FET Driver, powers the FETs based on inputs from
controller
Bridge FETs - gates drive power from the 5V supply to drive the resonant tank circuit (antenna)
Matching Network - array of capacitors to create the resonant tank along with the antenna
Antenna: Transmit - acts as the primary of an air-core transformer in conjunction with the receiver
antenna
Filters - adapt the antenna and drive values for use as feedback input to the controller, TS94033 as the
current amplifier.
