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 capacity batteries. The single cell charger has a single input that operates from either a USB port or AC wall adapter for a versatile solution. The battery is charged in three phases: tricklecharge, constant current and constant voltage.
