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 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.
