Faster charging, higher efficiency from wireless charging Rx

March 06, 2015 // By Graham Prophet
IDT’s P9027 claims shorter charging times and improved thermal performance; the wireless power receiver IC is packaged an ultra-compact form factor.

The P9027 magnetic induction receiver offers 80% peak system level efficiency and improved overall thermal performance. The high-efficiency architecture enables higher power transfer rates, translating into shorter charge times for portable devices. P9027 is an 8W receiver with compact solution size —approximately 37 square millimetres— and requiring six fewer capacitors than competitive products.

The device’s proprietary alignment guide optimises inductive coupling with the transmitter to maximise coil-to-coil power efficiency. The 3V to 7V adjustable output voltage range is capable of driving a variety of downstream power management ICs, while proprietary foreign object detection (FOD) ensures safe operation in the presence of metal objects.

In wireless power transmitter and receiver solutions for wireless charger applications, IDT says it addresses all major standards and technologies with a portfolio of standards-certified products, in both magnetic induction and magnetic resonance technologies, and actively participates in the Wireless Power Consortium (WPC), Power Matters Alliance (PMA), and Alliance for Wireless Power (A4WP) as a board member.
