Part Number: Qi-Wireless-Charging-LED-Lantern
REFERENCE DESIGN - QI® WIRELESS CHARGING LED LANTERN
Overview
The Microchip Qi wireless LED lantern is a lighting solution with wireless charging capabilities. It is able to draw up to 5W from a base station and charge a Li-Ion battery at 1A.
Battery charging is achieved using a bi-directional synchronous buck converter. The same converter can boost the battery voltage to drive a dimmable string of 3 LEDs at 200mA. A single 8 bit microcontroller manages the Qi communication, battery charging and LED driving, consequently simplifying the device and lowering the cost. Adding wireless charging capabilities to a portable lighting solution enables sealing the device and creating a water-proof or weather-resistant product.
