Description

12A, 18V, 500kHz, ACOT™ Synchronous Step-Down Converter.RT1650 is a fully integrated wireless power receiver, intended for wireless power in mobile devices up to 7.5W. This application note explains basic principles of Wireless Power Transfer, Wireless Power standards and the Qi WPC1.1 low power standard, and describes the features of RT1650. Several system aspects of a WPC1.1 5W application are presented by means of a practical example which uses a Nokia DT601 wireless power transmitter and the Richtek Wireless power receiver RT1650 evaluation board.
