50-W wireless power mobile reference design for 5G devices
Lion Semiconductor, Inc., is working with Renesas Electronics Corporation to develop ultra high-speed wireless charging systems up to 50 W for use in flagship smartphones and other mobile devices.

The Lion Semiconductor and Renesas reference design will help enable smartphone OEMs to quickly and cost effectively implement ultra-fast wireless charging on flagship smartphones, expanding the reach of wireless power technology. The system combines Lion Semiconductor's high efficiency switched-capacitor DC-DC converter with Renesas's high voltage wireless charger IC, enabling smartphones to wirelessly charge efficiently at ultra-high speeds with low heat dissipation.

"Through our collaboration with Lion for a higher power solution, consumers will enjoy the fast wireless charging experience on their next-generation 5G smartphones and other high-performance portable devices," said Amit Bavisi, Vice President of Wireless Power, Mobility Infrastructure and IoT Power Business Division at Renesas.

"Lion Semiconductor develops market leading high efficiency switched-capacitor charger ICs for fast charging.  Working with Renesas will help give more customers access to a fast, high efficiency wireless charging experience," said Wonyoung Kim, CEO of Lion Semiconductor.
