The STWLC38 is an integrated Wireless Power Receiver suitable for wearable/hearable and smart phone applications and can supply up to 15 W of outputpower. The chip has been designed to support Qi 1.3 specifications for inductive communication protocol, 5W Baseline Power Profile and 15W Extended PowerProfile. STWLC38 shows excellent efficiency performance thanks to the integrated low-losssynchronous 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.
