The LTC4125 wireless power transmitter, made by Linear Technology, brings performance and simplicity to the transfer of up to 5 W of power wirelessly to an electrically isolated receiver capable of that power level. It is a monolithic driver that controls the current flow in a series-connected transmit coil LC network.
The 4 x 5 mm, QFN-20 packaged chip features auto-resonant switching, allowing it to automatically adjust its driving frequency to match the LC network resonant frequency. It also implements foreign object detection, and auto-resonant switching improves performance with mismatched resonant components and poorly coupled coils. The LTC4125 completes a simple wireless power solution when combined with one of Linear’s wireless power receiver ICs.
