Page 6: Standard Use
Standard Use The TSDMTX-19V3-EVM is easy to set up and use. Use the power supply module and line cord that comes with the EVM kit to apply power to the EVM via “J2”, the 19V power input jack. Once input power is provided, the green LED should light for about a half-second and then turn off. - Page 7 EVM Receiver Tests Additional testing can be performed with the use of an EVM receiver module. There are a number of Semtech Receiver EVMs that support different power levels and output voltages, any of which can be used, as all support the Qi standard and therefore are compatible with the TSDMTX-19V3-EVM transmitter.
- Page 8 The following information is provided for reviewing how the EVM works in detail, as what can be observed below is entirely managed by the Semtech TS80003 Wireless Controller. It allows the observer an opportunity to see how the receiver and transmitter actively manage the wireless power process.
