EPC9129 - Wireless Power Demonstration System

Overview

TopologyBuck Converter
IC revision1.0

Description

The EPC9129 wireless power demonstration system is a high efficiency, AirFuel™ Alliance compatible, wireless power transfer demonstration kit capable of delivering up to 33 W into a transmit coil while operating at 6.78 MHzThe popularity of highly resonant wireless power transfer is increasing rapidly, particularly for applications targeting portable device charging. The end applications are varied and evolving quickly from cell phone charging, to handheld tablets, and laptop computers. The EPC9129 kit, capable of delivery up to 33 W supports all of these applications.

Features

An undervoltage-lockout circuit has been implemented for the inputvoltage (VIN). The amplifier board will not start unless VIN reaches itsminimum required value specified in table 1.A clamp diode also protects the board from VIN over-voltage for abrief period and accidental reverse polarity connection with up to
11 A current protection.
