Design files

Overview

This wireless power transmitter reference design is a practical layout in a compact 14mm X 22mm (280mm sq) area. The solution uses the bq500511 digital chip and bq50002 analog front end Gen3 transmitter solution, combined to provide ease of use and product quality with a cost competitive solution.  The design is targeted at low power wearable solutions with small receiver coils such as personal electronics, industrial and medical systems.

Features
  • 1W Wireless Power Transmitter
  • 0.43 sq in ckt layout area
  • Design will support small transmitter coil for improved operation with small receiver coils.
  • Low Cost Two IC solution
  • Low System Standby Power during Ping. Only 30 mW
  • 63% Peak System Efficiency
