AAT3183
300mA Inductorless Step-Down Converter

General 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
topology provides enhanced efficiency over conven-
tional 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.
The AAT3183 soft-start prevents excessive inrush
current while providing monotonic turn-on charac-
teristics. The device includes integrated short-cir-
cuit 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.
