PTX130W NFC Wireless Charging IC Renesas Electronics PTX130W NFC Wireless Charging IC is a powerful and efficient near-field communication (NFC) transmitter system-on-chip (SoC) for wireless charging applications alongside data communication. PTX130W features improved key performance parameters such as output power and RX sensitivity (-80dBc ). While eliminating EMC filter and matching components the PTX130W enables simple integration and compact design without the complexity associated with existing solutions (dual resonating circuits composed by EMC filter and antenna). The superior RF performance of PTX130W enables small antenna design, fast charging and allows flexible placement of Poller and Listener antennas.
