ISL6253, Highly Integrated Battery Charger

DATASHEET ISL6253 Highly Integrated Battery Charger for Notebook Computers FN9117 Rev.2.00 August 2004 The ISL6253 is a highly integrated battery charger controller for Li-Ion/Li-Polymer batteries.

High Efficiency is achieved by a synchronous buck topology and the use of a MOSFET, instead of a diode, for selecting power from the adapter or battery.

The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting.

The constant output volt
