NXP shows Worlds Smallest 5V Qi Wireless Charger

Posted by Charbax – March 10, 2014

NXP Semiconductors demonstrates their new Qi wireless charging transmitter device, which integrates all the circuits for a 5V mobile phone charger in an extremely small package measuring only 5-mm square. Using the NXP solution, fewer than 10 external components are needed to build a complete low-power 5V Qi A5/A11 wireless charging transmitter, alongside the Qi coil and resonant capacitors. The small footprint of the NXP NXQ1TXA5 system-on-chip means that the whole transmitter sits on a PCB of less than 1.5 cm-square with components on a single side. This opens up interesting possibilities for innovative wireless charging pad designs, including fitting the transmitter within the center of the Qi coil.
