Manufacturer: STMicroelectronics

Overview: STWLC68 Datasheet Qi-compliant inductive wireless power receiver for 5W applications Product status link STWLC68 Product summary Order code STWLC68JRH Package WLCSP72 Packing Tape and.

General Description

The STWLC68 is an integrated Wireless Power Receiver suitable for portable applications and capable of managing up to 5 W of output power.

The chip has been designed to support Qi 1.2.4 specifications for inductive communication protocol and Base Power Profile (BPP).

The STWLC68 shows excellent efficiency performance thanks to the integrated lowloss 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.
