LTC4125 Datasheet 5w Autoresonant Wireless Power Transmitter

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC4125 5W AutoResonant Wireless Power Transmitter.

General Description

The LTC®4125 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 the current flow in a series connected transmit coil LC network to create a simple, safe and versatile wireless power transmitter.

The LTC4125 automatically adjusts its driving frequency to match the LC network resonant frequency.
