S T E VA L - I S B 0 3 9 V 1 1 W wireless charger system Tx/Rx based on STM32F0 and STWLC03 Data brief Main features of receiver: integrated high efficiency synchronous rectifier integrated 1 MHz programmable buck converter with input current and input voltage regulation loops Simplified Li-Ion/Polymer charger function RoHS compliant Description The STEVAL-ISB039V1 is a wireless battery charger evaluation kit based on the STM32F0 microcontroller for wireless battery charger transmitters and the STWLC03 integrated wireless power receiver. The STEVAL-ISB039V1 solution is primarily designed for small systems up to 1 W that can be recharged easily, and can be adjusted for 2.5 W. For the wireless power transmitter, the firmware consists of a single STM32CubeMX platform- independent library providing a simple and easily Features customizable solution for the design of wireless STM32F0 for wireless power transmitter and power transmitters with proprietary features. STWLC03 for wireless power receiver The STWLC03 receiver can deliver the output 1 W output power power in two modes: as a power supply with WPC 1.1 based communication protocol configured output voltage or as a simple CC-CV Main features of transmitter: battery charger with configurable charging high efficiency N-channel Half Bridge current, charging voltage and termination current. architecture with adaptive dead-time control The IC interface allows the customization of parameters in the device and and the storage of synchronous digital demodulation of power carrier, reduces BoM configurations in the embedded non-volatile memory. considerably standard or enhanced power transmitter coil coil temperature monitoring through NTC MCU firmware open for customization built-in USB connector for input supply voltage September 2016 DocID029715 Rev 1 1/7 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams STEVAL-ISB039V1 1 Schematic diagrams Figure 1: STEVAL-ISB039V1 circuit schematic of transmitter (1 of 3) GSPG0108161455SG 2/7 DocID029715 Rev 1
