STWLC68JRH High-Efficiency Wireless Power Receiver

STMicroelectronics' STWLC68JRH high-efficiency wireless power receiver is suitable for portable applications and is capable of managing up to 5 W of output power. The device has been designed to support Qi 1.2.4 specifications for inductive communication protocol and base power profile (BPP). The STWLC68JRH shows excellent efficiency performance thanks to the integrated low loss synchronous rectifier and the low drop-out linear regulator; both elements are dynamically managed by the digital core to minimize the overall power dissipation over a wide range of output load conditions.

Through the I²C interface, users can access and modify different configuration parameters, tailoring the operation of the device to the needs of custom applications. The configuration parameters can be saved in the embedded OTP memory and automatically retrieved at power-up, allowing the STWLC68 to operate as a standalone device. The STWLC68 is housed in a chip-scale package to fit real-estate solutions in wearable devices.
