NCP1871 Narrow Voltage DC Battery Charger The NCP1871 is a NVDC switching battery charger designed for 2 3 4 battery cell applications such as ultra books or tablets.

It is optimized for use with the mobile computing chipsets, and is also compatible with most mobile solutions.

The NCP1871 is designed around a full NMOS DC to DC controller that brings down the high voltage charger adapter voltage to a regulated system supply that is in the same range as the battery pack voltage.
