Description:

LTC4120, LTC4125 Wireless Power Supply/Charging Power Management Evaluation Board.

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 LTC4120-4.2 is suitable for charging Li-Ion/Polymer batteries, while the programmable float voltage of the LTC4120 accommodates several battery chemistries. The LTC4120 uses a Dynamic Harmonization Control (DHC) technique that allows high efficiency contactless charging across an air gap. 

Features:

• Dynamic Harmonization Control Optimizes
  Wireless Charging Over a Wide Coupling Range
• Wide Input Voltage Range (12.5V to 40V)
• Adjustable Float Voltage (3.5V to 11V)
