The LTC4120 is a constant-current/constant-voltage wireless receiver and battery charger. The charge current is programmed up to 400mA with an external resistor. If more than 400mA is required, then use two LTC4120 devices operating in parallel as shown in this schematic. In this case the two LTC4120 operate from one transmitter ...

LTC4120 Wireless Power Receiver and 400mA Buck Battery Charger

Oct 4th 2013
The LTC®4120 is a constant-current/constant-voltage wireless receiver and battery charger. An external programming resistor sets the charge current up to 400mA. The programmable float voltage of the LTC4120 accommodates several battery chemistries. The LTC4120 uses a Dynamic Harmonization Control (DHC) technique that allows ...
