AAT3183中文资料300mA Inductorless Step-Down Converter数据手册Skyworks规格书

描述 Description

The AAT3183 is a high efficiency step-down charge pump converter providing up to 300mA of output current. The 1/2x (gain) charge pump converter opology 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.
The 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 when the device is disabled.
The AAT3183 soft-start prevents excessive inrush current while providing monotonic turn-On characteristics. The device includes integrated short-circuit and over-temperature (thermal) protection to safeguard system components.
The AAT3183 is available in a Pb-free 2.0x2.1mm SC70JW-8 package. Operating temperature range is -40ºC to +85ºC.
