EUP8207-4.2 Datasheet (Eutech Microelectronics) - Switch Mode Li-Ion/Polymer Battery Charger

EUP8207-4.2, Switch Mode Li-Ion/Polymer Battery Charger

The EUP8207 is a constant current, constant voltage Li-Ion battery charger controller that uses a current mode PWM step-down (buck) switching architecture.

With a 500kHz switching frequency, the EUP8207 provides a small, simple and efficient solution to fast charge one (4.2V) or two (8.4V) cell lith
