产品概述
描述
The STDES-70WRXWLC is a reference design that implements the Qi-compliant inductive wireless power receiver. The solution supports the Qi EPP compliant mode up to 15 W. With the proprietary ST super charge (STSC) protocol, the solution delivers an output power of up to 70 W.
The STDES-70WRXWLC is based on the STWLC98 high-integration, high-performance wireless power receiver system-on-chip, with an integrated 27 V low-loss synchronous rectifier and a low drop-out linear regulator. The device can also operate as a wireless transmitter up to 15 W (coil-dependent and input voltage).
The STDES-70WRXWLC is a fully assembled kit developed for performance evaluation only, not available for sale.
