PRODUCT DATASHEET AAT3183 AAT3183 ChargePump 300mA Inductorless Step-Down Converter General Description Features The AAT3183 AAT3183 is a high efficiency step-down charge pump converter providing up to 300mA of output current. The 1/2x (gain) charge pump converter topology provides enhanced efficiency over conventional LDO regulators and requires only three low cost ceramic capacitors. No inductor is required; saving space and cost when compared to inductive switching regulators. · · · · TM · · · · · · · · · The AAT3183 AAT3183 typically consumes 35µA of no load (zero output current) quiescent current, making it ideal for portable battery powered systems. Shutdown current is less than 1µA. The AAT3183 AAT3183 soft-start prevents excessive inrush current while providing monotonic turn-on characteristics. The device includes integrated short-circuit and overtemperature (thermal) protection to safeguard system components. VIN Range: 2.7V to 5.5V VOUT: 1.5V and 1.34V 300mA Maximum Output Current Ultra-Small Solution for Portable Applications Small Footprint Only Three External Ceramic Capacitors Required No Inductor High Efficiency over the Output Current Range Excellent Transient Performance 35µA Typical Quiescent Current
