ROHM has received certification from WPC (Wireless Power Consortium) for its reference design using the BD57020MWV wireless power transmitter IC. This is the first device in the world certified to be compliant with the new Qi medium power specification.

WPC’s Qi standard for medium power has attracted attention as a next-generation standard for inductive power transmission that will enable wireless charging of tablet PCs while allowing smartphones and other mobile devices to be charged up to 3x faster than the existing low power standard (5W).

In addition to pioneering the development of a wireless power transmitter IC (BD57020MWV) compliant with the Qi medium power specification, ROHM has developed a reference design that is expected to not only facilitate the introduction of wireless charging in new applications requiring higher power, but also accelerate adoption in applications that can benefit from wireless charging.
