LTC4125EUFD#PBF

The LTC4125EUFD#PBF is a 5W AutoResonant wireless power transmitter in 20 pin QFN package. The LTC4125 is a simple and high performance monolithic full bridge resonant driver capable of delivering over 5W of power wirelessly to a properly tuned receiver. The device controls current flow in a series connected transmit coil LC network to create simple, safe and versatile wireless power transmitter. The LTC4125 automatically adjusts its driving frequency to match LC network resonant frequency. This AutoResonant switching allows device to deliver maximum power from a low voltage input supply to a tuned receiver. To optimize system efficiency, it employs a periodic transmit power search and adjusts the transmission power based on the receiver load requirements. The device stops delivering power during a fault condition or if a foreign object is detected. It is used in hermetically or electrically insulated devices, military sensors and devices, medical equipment and industrial handhelds.
