Description
TS51231 is a transmitter driver and output stage for wireless charging applications. It can
support systems up to 5W output. Switching of the TS51231 is controlled by the wireless
power transmitter controller (TS80002 or similar). TS51231 Tx EVM is a transmission
evaluation board for wearable application. All the necessary function components occupy
a 10mmX13mm of PCB area.
The wireless power Rx board should be work together with Tx board. The maximum
output power of Rx EVM is 2W at 5V.
Jumper introduction
1. Tx board is rectangle and Rx board circler;
2. J1 on Tx board is input port and J1 on Rx board output port;
3. Short J2 jumper on Rx board can light LED1 to indicate output voltage, J2 should be
open when conducting efficiency testing;
Operation Instruction
1. Connect 12Vin into J1 of Tx board;
2. On Rx Board, Connect e-load to J1 between VOUT+ and GND;
3. Set the required output current (0A-400mA) with electrical loads in CC mode;
4. place Rx board onto the top of Tx board, aligning to the circular edge; In order to get
the maximum output power and efficiency, Rx board must be located right above the
Tx coil and the space between Tx & Rx coils should be ~4mm.
