WPC 1.1 and PMA 1.1 Dual-mode Wireless Power Receiver
Integrated Device Technology (San Jose, CA) has announced the industry’s first dual-mode wireless power receiver compatible with both the Wireless Power Consortium’s (WPC) 1.1 Qi standard, as well as the Power Matter’s Alliance (PMA) 1.1 standard. The innovative solution enables OEMs to use a single wireless power receiver IC to develop mobile devices fully compatible with the latest versions of both Qi and PMA charging bases. The IDTP9023 is a WPC 1.1- and PMA 1.1-compliant single-chip wireless power receiver consisting of:
- A synchronous full-bridge rectifier.
- High-efficiency synchronous buck converter.
- Embedded microcontroller used to optimize power delivery to the mobile device’s load, while minimizing application footprint, component count, and thermal dissipation.
