New Reference Design Expands Best-in-Class Wireless Charging for Mass Market Devices; Solution for 5G Smartphones Available Now
Renesas Electronics Corporation has expanded its ongoing work with Qualcomm Technologies, Inc., to include 30W wireless charging capabilities for mid-range smartphones powered by the latest Qualcomm Snapdragon 780G 5G Mobile Platform. This is the second high-power wireless charging smartphone reference design collaboration for the two companies. The first solution, designed for flagship devices, is sampling commercially now. This latest phase is a significant step that extends the global leaders’ collaboration to bring highly integrated, advanced wireless power features as a standard feature in 5G smartphones from flagship to mainstream devices.
Qualcomm Technologies’ 5G mobile reference designs provide turnkey solutions that are intended to facilitate smartphone OEMs to quickly and cost effectively implement fast wireless charging on flagship and mid-range smartphones, with Multi-Time Programmability (MTP) and OTA updates to simplify software development and Qi certification process. The Renesas solution offers the highest integration with over 85% end-to-end system efficiency to help expand the reach of wireless power technology to an even broader set of customers and simplify the process of adding wireless charging.
The Renesas P9412 wireless power receiver is the industry’s first 30W power receiver with a high voltage integrated capacitor divider, offering superior power efficiency with 40-percent reduction in solution size compared with conventional solutions and freeing up PCB area for customers to include other features. For a safe and fast charging experience, a custom high-power protocol is embedded in the device firmware, allowing the system to authenticate power transfer beyond the 15W defined by WPC EPP standard. Renesas’ Wattshare technology enables the mobile device to become a power source and wirelessly charge accessories in the ecosystem, such as earbuds and smart watches.
