ISL6252 Highly Integrated Battery Charger Controller

® ISL6252, ISL6252A Data Sheet August 25, 2010 FN6498.3 Highly Integrated Battery Charger Controller for Notebook Computers The ISL6252, ISL6252A is a highly integrated battery charger controller for Li-ion/Li-ion polymer batteries. High Efficiency is achieved by a synchronous buck topology. The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting. The constant output voltage can be selected for 2, 3 and 4 series Li-ion cells with.
