The ISL6255EVAL2Z (QFN) evaluation kit includes 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 and 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.
