- PTX130W offers industry’s highest output power for faster NFC charging
- With system efficiency 18% higher than Panthronics’ first-generation transmitter, the PTX130W improves design flexibility for manufacturers of small consumer devices
- The new product benefits from Panthronics’ sine-wave architecture to offer simpler antenna matching, a smaller BoM and high tolerance of antenna misalignment
Graz, Austria – Panthronics AG, a fabless semiconductor company specializing in high performance wireless technology, today launched the PTX130W, a new improved version of the PTX100W NFC charging transmitter, or ‘poller’, which offers higher efficiency to enable easier implementation of fast NFC charging in small device designs.
The PTX130W achieves on-chip efficiency which is 18% better than that of the PTX100W. Harvested power at the listener is 1W, twice as high as the best competing system can achieve.
Higher system efficiency gives new design options to manufacturers of products such as fitness trackers, smart watches, earbuds, hearing aids, smart glasses, smart rings, styluses and medical sensors. The reduction in power losses and waste heat allows designers to shrink a product’s enclosure, and to remove thermal management materials while maximizing the power input to the battery.
The PTX130W’s improved efficiency is the result of enhancements to the IC’s power amplifier, and improved packaging including dedicated Transmit and Receive pins.
Mark Dickson, Chief Marketing Officer of Panthronics, said: ‘Panthronics continues to achieve new breakthroughs in the NFC wireless charging market. Building on the success of the PTX100W poller, the new PTX130W gives OEMs the means to increase the value of their products – it enables faster charging of bigger batteries to give users greater convenience and more hours of usage on demand.’
Multiple power-saving features
The PTX130W includes various features which save power, helping to extend the operating time of battery-powered charging cradles. An automated power control loop optimizes system efficiency. The PTX130W also includes a low-power embedded listener detection circuit, drawing just 100µA at a 2Hz polling rate. In addition, 20-step power negotiation in charging mode enables optimization of power dissipation.
The PTX130W shares the unique Panthronics sine-wave architecture first deployed in the first-generation PTX100W NFC poller. This architecture eliminates the lossy EMC filter required in conventional square-wave NFC architectures, and allows for a direct connection between the transmitter and antenna. This gives many benefits including:
- More flexibility in the placement of the charger and device antennas relative to each other. This eliminates the need for bulky alignment magnets.
- Fewer components for a smaller system footprint, and very little variation in performance between production units.
- Simpler and quicker antenna matching and system certification.
The PTX130W NFC poller is supplied in a 7mm x 7mm QFN56 package. Engineering samples are available directly from Panthronics.
