Wireless Charging Receiver

NU1619A

NU1619A is a highly integrated and highly efficient wireless power receiver. It integrates a synchronous rectifier designed for a wide frequency range and a programable low dropout regulator for the optimal system efficiency. The regulator can provide a wide range regulated voltage or current output; both can be programmable through an I2C interface. NU1619A can conduct bi-directional communication with a transmitter system through ASK and FSK. The communication is compliant with WPC. NU1619A can also be operated as a transmitter (Tx) to charge another receiver. Only few external components are needed and maximum 10W power can be transferred.
