STWLC38 and STWBC86 based Tx and Rx eval boards for Qi wireless chargers
To support quick development of Qi-compliant wireless chargers up to 15W, STMicroelectronics has launched transmitter and receiver evaluation boards based on it's STWLC38 and STWBC86 Ics.
Below are the more details shared by the company in its latest release: The STEVAL-WLC38RX board containing the STWLC38 5W/15W receiver IC and STEVAL-WBC86TX containing the STWBC86 5W transmitter help quickly build and test wireless-charger prototypes. Both are used with the STSW-WPSTUDIO graphical software environment to assist development. The STWLC38 receiver IC supports the Qi 1.3 15W Extended Power Profile (EPP) and 5W Baseline Power Profile (BPP). It can also perform as a 5W transmitter and allows reverse power transfer for device-to-device charging. Integrating a synchronous rectifier and low-dropout (LDO) linear regulator, the IC converts power from the receiver coil to a programmable 4V-12V DC output voltage, with power-transfer efficiency of 85%. ST’s Adaptive Rectifier Configuration (ARC) mode, which maximizes the usable charging area, extends the typical receiver-detection distance by 50% and increases spatial freedom to position devices for optimal power transfer. The STWBC86 Qi 1.2.4 BPP-compatible 5W transmitter integrates a high-efficiency, low-impedance full-bridge inverter and...
