Wireless Power Design Kit – Medium Power – 760308MP V1.0
Design Kit Manual
EUDC59-U-004 - Rev. 1.0
The MCU on the receiver side is required for the proper configuration of the RX IC. Without the configuration the RX is not sending
the needed parameters during the negotiation/calibration phase to enable the medium power transfer mode. The I2C interface is
used to set the necessary parameters such as the LDO output voltage, the current limit, FOD and QFOD settings.
The receiver system of this design kit uses a modular approach: The Load Module is designed as stackable shield on top of the
Receiver Module. This allows easy replacement of the demonstrative LED matrix load and receiver side MCU. The user may design
a custom load/MCU shield or connect to the RX Module pin headers by jumper cables.
Interoperability between transmitter and receiver is achieved by complying with the WPC Qi standard. The Transmitter Module can
supply power to any Qi compliant receiver and equally the Receiver Module can receive power from any Qi compliant transmitter.
Also, both modules are backwards compatible with a low power (baseline power profile) counterpart.
2.2 Key components
