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 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.

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 stand-

alone device.

The STWLC68 is housed in a Chip-Scale Package to fit real-estate solutions in

wearable devices.
