10 W Multi-Mode Wireless Power System

Overview

TopologyWireless Power Transfer
Input voltage19 V
Switching frequency165-6780 kHz
Output 138 V / 1.5 A
IC revision1.0

Description

The EPC9121 is provided with two receive device units: The first is tuned to and compatible with the AirFuel Category 3 specification and the second is an inductive mode unit compatible with the 5 W Qi receiver standard. Each of the device units includes a high frequency schottky diode based full bridge rectifier and output filter to deliver a filtered unregulated DC voltage. The device board comes equipped with two LED’s, one green to indicate the power is being received with an output voltage equal or greater than 4 V and a second red LED that indicates an overvoltage condition where the output voltage exceeds 36 V.
