STWLC03:Dual-mode Qi/ PMA wireless power receiver

The STWLC03 is an integrated wireless power receiver solution suitable for portable applications. The STWLC03 is able to operate with Qi 1.1 or PMA communication protocol. Thanks to the integrated low impedance synchronous rectifier and DC-DC step-down converter, the STWLC03 achieves high efficiency, low power dissipation and output power beyond 5 W. Digital control and precise analog control loops ensure stable operation. I2C interface allows many parameters to be customized in the device and this configuration can be stored in the embedded NVM.

The STWLC03 can deliver the output power in two modes: as a power supply with configured output voltage or as a simple CC/CV battery charger with configurable charging current.

The STWLC03 can detect an external (wired) power supply connection and drive an external power switch.
