STMicroelectronics STWBC86JR | Demoboard STWBC86 5W Tx Typical Application

Qi compatible wireless power transmitter for 5W applications with integrated full bridge

Overview

TopologyWireless Power Transfer
Output 15 V / 1 A
IC revision1

Description

The STWBC86 is a highly integrated monolithic wireless power transmitter solution suitable for applications up to 5W.This solution requires low external BOM count. Because of the integrated low impedance Full/Half bridge inverter, STWBC86 achieves high efficiency and low power dissipation.I2C interface allows firmware and platform parameters to be customized and the device can be configured using the embedded FTP. Additional firmware patching also improves application flexibility of STWBC86.The Flip Chip package and low BOM count make the device suitable for very compact applications.
