LTC4001-1 Datasheet 2a Synchronous Buck Li-ion Charger

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC4001-1 2A Synchronous Buck Li-Ion Charger.

General Description

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 wide range of handheld applications.
