IDTP9020
Multi-Mode WPC Compliant Wireless Power Receiver IC
The IDTP9020 is a highly-integrated single-chip WPC-compliant wireless power receiver IC. The device receives an AC power signal from a compatible wireless transmitter and converts it into a regulated 5V output voltage which can be used to power devices or supply the charger input in mobile applications. The IDTP9020 integrates a high-efficiency synchronous full-bridge rectifier, high-efficiency synchronous buck converter, and control circuits used to modulate the load to transmit WPC-compliant message packets to the transmitter station to optimize power delivery. Power delivery is limited to 5W in accordance with the Qi specification.
