ISL6255EVAL1Z, ISL6255EVAL2Z

Highly Integrated Battery Charger with Automatic Power Source Selector Evaluation Boards

Description

The ISL6255EVAL1Z (QSOP) and ISL6255EVAL2Z (QFN) evaluation kits include all the circuitry needed to demonstrate the capabilities of the ISL6255 lithium-ion battery charger

The ISL6255 is a highly integrated 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.
