Wireless Charging Receiver
NU1652
NU1652 is a highly integrated and efficient wireless power receiver and suitable for up to 70W output power application. It integrates a synchronous rectifier and a programable low drop-out regulator. The regulator can provide a wide range regulated voltage. NU1652 can conduct bi-directional communication with a transmitter system through ASK and FSK. The communication is compliant with WPC. NU1652 can also be operated as a transmitter (Tx) to charge another receiver. Only a few external components are needed and maximum 15W power can be transferred.
