IA3220 Overview
The IA3220 L are high-efficiency, high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 1.3A output currents. The IA3220 can operate over a wide input voltage range from 2.3V to 6V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery.
