ISL6255AHAZ-T - Renesas Electronics

Description: The ISL6255 and ISL6255A are highly integrated battery charger controllers 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. The constant output voltage can be selected for 2, 3 and 4 series Li-Ion cells with 0. 5% accuracy over temperature. It can a
