Semtech LKCH-TXRX40W-EVB
The LKCH-TXRX40W-EVB wireless charging solution includes one transmitter and one receiver. The transmitter is named “Semtech TSDMTX-24V3-EVM” which is an evaluation platform for test and experimentation of a wireless charging solution based on the Semtech TS80003 Wireless Power Transmitter Controller, TS61002 FET Driver, TS30041 DC/DC Converter, and TS94033 Current Sense Amplifier.
This evaluation module provides a complete system solution and is compatible with the Wireless Power Consortium (WPC) or Qi standards of power transmission, making this transmitter an ideal platform for powering the majority of wireless receivers in use today. The receiver is named “Semtech TSDMRX-19V/40W-EVM” which is an evaluation platform for test and experimentation of a high power wireless charging receiver based on a suite of high efficiency Semtech ICs: the TS80003 Receiver Controller for Wireless Power Systems, TS61002 Driver, TS30041 Buck Regulator and the SC508 Buck Regulator Controller. This evaluation module, in conjuction with the TSDMTX-24V3-EVM, provides a complete system solution for the transmission of high power and charging of batteries with high energy capacity.
While Linkcharge 40 is capable of charging devices at 40W, it is also backwards compatible and capable of charging smartphone at either 5W or fast charge power levels. This allow users to charge a smartphone on the same transmitter that is also used for higher power 40W devices.
