ISL6257規(guī)格書詳情
Highly Integrated Narrow VDC Battery Charger for Notebook Computers
The ISL6257 is a highly integrated battery charger controller for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for Narrow VDC applications where the system power source is either the battery pack or the regulated output of the charger. This makes the max voltage to the system equal to the max battery voltage instead of the max adapter voltage. Operating at lower system voltage can improve overall efficiency. High efficiency is achieved in the charger with a synchronous buck topology. The low-side MOSFET emulates a diode at light loads to improve the light loadefficiency and prevent system bus boosting.
