XKT-412 Datasheet – IC for Wireless Power Supply Module

Part Number : XKT-412

Function : 5V1A USB Large current wireless power supply module

Package :  DIP 8 Pin Type

Manufactures :


XKT-412 wireless chip


The Wireless Power Transfer and Charging Module can be used in electronic equipments in Common use for close wireless charging or power supply. Consist of a Transmitter & Receiver and coil, it could serve as a replacement for the Wireless Power Supply with stable 5V output Voltage and maximum 600mA output current. Its small size and insulation coil is more suitable for using in wireless project. This module use an electromagnetic field to transfer electric energy between a transmitter circuit and a receiver circuit. An induction coil creates an alternating electromagnetic field from within the transmitter circuit powered with 12V. The second induction coil takes power from the electromagnetic field and converts it back into electrical current to the receiver circuit that outputs 5V – 600mA.
