General Description

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.

Key Features

  • High Efficiency: Up to 96% 1.5MHz Constant Frequency Operation 1300mA Output Current No Schottky Diode Required 2.3V to 6V Input Voltage Range Adjustable Output Voltage Range Options from 0.6V to Vin 100% Duty Cycle Low Dropout Operation Low Quiescent Current: 35µA Slope Compensated Current Mode Control for Excellent Line and Load Transient Response Short Ci.
