Beschreibung
Demonstration Kit DC3080-KIT features LTC®4126ADJ, wireless Li-Ion Charger with 1.2V Step-Down DC/ DC Converter. This kit comprises a wireless transmitter DC3081A, a wireless receiver DC3078A and two 6mm application-sized receivers DC3079A. DC3078A wireless charger receiver incorporates an external trickle charge circuit that reduces the charge current to 1mA when a deeply discharged battery with voltage lower than 2.8V is plugged in. The combination of DC3081A transmitter and DC3078A receiver can charge a single Li-Ion battery at up to10mA with an airgap of 4.0mm to 8.0mm.
