PTX100W is able to achieve its class-leading output power thanks to its patented sine wave architecture. With the elimination of EMC filter, a lower antenna matching impedance can be achieved, which is two times lower compared with the conventional solution. These two features enable the PTX100W NFC charger to drive much higher power through an NFC antenna than existing NFC ICs can do, while minimizing the power losses introduced by external components.

NFC Wireless charging IC
Panthronics´ PTX100W supplies up to 1W to the listener battery.
The industry’s first dedicated NFC transmitter for wireless charging applications alongside data communication.
PTX100W is a powerful and efficient NFC transmitter system-on-chip for use in wireless charger devices for consumer application.
Its new RF architecture enables NFC wireless charging solutions of devices with smaller antenna and larger battery capacity compared to the existing solutions.
Wireless Charging System Reference
The system reference includes:
- On the poller side:
- the PTX100W NFC controller from Panthronics
- an MCU for system control
- On the listener side:
- a NFC Tag for NFC data transfer
- an efficient rectifier circuit
- a PMIC for battery charging
- MCU for WLC protocol implementation
Wireless Charging System Performance
- Highly automatized and robotized test environment to characterize NFC Wireless Charging systems in different conditions:
- Within full operating volume
- Under various corner conditions (temperature…)
- Under different charging states (trickle charge, CC and CV)
- The performance tests on PTX WLC Evalkit proves 1W harvested power on listener over arbitrary misplacement of ±5mm in x/y at various z positions.
