ISL6255HAZ

高度集成的电池充电器具有自动电源选择器，用于笔记本电脑 Highly Integrated Battery Charger with Automatic Power Source Selector for Notebook Computers

The ISL6255, ISL6255A is a highlyintegrated battery charger controller for Li-Ion/Li-Ion 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.
