Introduction The Semtech TSWITX-G4-EVM is an evaluation platform for the test and experimentation of a wireless charging transmitter based on the Semtech TS80002 Wireless Power Transmitter Controller and TS51231 Transmitter Controller. This evaluation module, in conjunction with its compatible receiver, the TSWIRX-5V2-EVM or TSWIRX-LI-EVM, provides a complete system solution for low-power, wearable infrastructure power transmission. -

High power wireless systems are intended to support devices such as power tools, radio controlled (“RC”) devices such as drones, and other equipment requiring 15 to 100 watts of power. www.semtech.com TSWITX-G4-EVM 2 of 18 User Guide Rev 1.00... -
Page 4: Product Description
The TSWITX-G4-EVM Evaluation Module is a ready-to-use demonstration platform allowing testing of approximately 1.25 watt of wireless power transmission. The transmitter is coupled with its compatible receiver module, the Semtech TSWIRX-5V2-EVM, to form a complete wireless power transmission system. TSWIRX-5V2-EVM can output 5V/250mA max in this system. -
Page 5: Standard Use
Standard Use The TSWITX-G4-EVM is easy to set up and use. Connect a USB cable from any USB port capable of driving up to 2 watts (most PCs will suffice) to the USB port on the EVM. On application of power, the green LED should light, indicating the board is now active. - Page 6 ‘transmitter antenna’). Once transmission begins, you should observe approximately 5 volts and 0 amperes on the meters. Then turn the Electronic Load from 0mA to 250mA, you can observe the Vout is constant. www.semtech.com TSWITX-G4-EVM 5 of 18 User Guide Rev 1.00...
- Page 7 The following information is not required in order to use the EVM, as what can be observed below is entirely managed by the Semtech TS80002 Wireless Controller. However, it allows the observer an opportunity to see how the receiver and transmitter actively manage the wireless power process.

B. Schematic Below are two copies of the schematic for the TSWITX-G4-EVM. The first will be best when viewed on- screen, as it is normally oriented and can be zoomed in on for readability. The second will allow better use in print-out form, as the landscape orientation allows a larger image to be provided. For each, annotation has been added to indicate which part of the block diagram each component is a member of. - Page 10 VCC5V VCC5V PWM1_L PWM1_H 100nF PWM2_L 100nF 4.7nF 10nF PWM2_H BOOT 6.3V 6.3V 22nF V_AC TX Coil I_DC GPIO1 VREF GPIO2 V_DC GPIO3 HSON GPIO4 nFLT PGND DONE ALERT PGND 4.7nF RESET SMB_SCL NRST DEBUG SMB_SDA TS51231 DEBUG TS80002 VCC5V 330K 100nF RESET...
- Page 11 Bill Of Materials “BOM” Below is a listing of the parts used in the TSWITX-G4-EVM. Note that only a few dozen components were required to implement the complete transmitter solution. An excel spreadsheet file with this information is available on the Semtech website as an added convenience.

Page 12: Board Layout
C. Board Layout The diagram below shows the locations of the components used in the TSWITX-G4-EVM PCB. Note that the transmitter solution itself fits easily inside a 10x14mm rectangle with single-sided construction. Smaller layouts can readily be created if required. -
Page 13: Board Layers
D. Board Layers The TSWITX-G4-EVM PCB is based on a four layer design as shown below. The ground plane in layer two is recommended to reduce noise and signal crosstalk. The EVM placed all components on the top of the board for easier evaluation of the system. End product versions of this design can be made significantly smaller by distributing components on both sides of the board. -
