LTC4001-1 Datasheet (Linear Technology) - 2A Synchronous Buck Li-Ion Charger

LTC4001-1, 2A Synchronous Buck Li-Ion Charger

The LTC®4001-1 is a 2A Li-Ion battery charger intended for 5V wall adapters.

It utilizes a 1.5MHz synchronous buck converter topology to reduce power dissipation during charging.

Low power dissipation, an internal MOSFET and sense resistor allow a physically small charger that can be embedded in a w
