2A Synchronous Buck Single Cell Li-Ion USB/Adapter Charger CE3320 Series INTRODUCTION: The CE3320 is a highly integrated standalone switch mode single-cell Li-Ion battery charger.

It utilizes a 1.5MHz synchronous buck converter topology to reduce power dissipation during charging.

Low power dissipation, an internal integrated MOSFET and current sense resistor allow a physically small charger that can be embedded in a wide range of space-limited portable applications with high capacit
