IDTP9021
Dual-mode Wireless Power Receiver IC
The IDTP9021 is a dual-mode single-chip wireless power receiver IC that complies with the requirements of both WPC “Qi” 1.0.1 and PMA Type 1 Interoperability specifications. The device functions to receive an AC power signal from a compatible wireless transmitter and convert it into a regulated 5V output voltage to provide direct power or supply the charger input in mobile applications. The IDTP9021 integrates a high-efficiency synchronous full-bridge rectifier, high-efficiency synchronous buck converter, and control circuits used to modulate the load to transmit WPC or PMA-compliant message packets to the transmitter to optimize power delivery.
