The is a switched-capacitor charge-pump Voltage Inverter with shutdown which may be used to generate a negative supply from a positive input. Input voltages ranging from 1.5 to 5.5V can be inverted into a negative -1.5 to -5.5V output supply. This inverting scheme is ideal for generating a negative rail in single power-supply systems. Only two small external capacitors are needed for the charge-pump. Output currents up to 25mA with greater than 99% efficiency are achievable. The ADM8828 also features a low power shutdown SHDN pin. This can be used to disable the device and reduce the quiescent current to 20nA.
