A AX1H0X10717 1.8A high Efficiency Step-down Converter Features Up to 90% Conversion Efficiency Typical Quiescent Current: 40 µA Load Current: up to 1.8A Operating Input Voltage Range: 2.5 V to 5.5 V Switching Frequency up to 1MHz Adjustable and Fixed Output Voltage 100% Duty Cycle for Lowest Dropout Internal Soft Start Thermal Shutdown Short-Circuit Protection SOT-23-6L Package Application CPUs and DSPS PC Cards and Notebooks Standard 5V to 3.3V Conversion PDA, Pocket PC and Smart Phones USB Powered Modems Description The AX1017 family of devices is high efficiency synchronous step-down dc-dc converters optimized for battery powered portable applications. The devices are ideal for portable applications powered by a single Li-Ion battery cell or by 3-cell NIMH/NICD batteries. With an output voltage range from 5.0 V down to 0.7 V, the devices support low voltage DSPS and processors in PDAS, pocket PCs, as well as notebooks computers. The AX1017 operates at a fixed switching frequency.
