3A Synchronous Step-Down Converter 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 Circuit Protection Thermal Fault Protection Inrush Current Limit and Soft Start <1µA Shutdown Current Tiny SOT23-5 Package 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.
The output voltage can be regulated as low as 0.
6V.
The IA3220 L can also run at 100% duty cycle for low dropout operation, extending battery life in portable system.
This device offers two operation modes, PWM mode and PFM Mode switching control, which allows a high efficiency over the wider range of the load.
The IA3220 L is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in an adjustable version.
