LTC1144 Datasheet (Linear Technology) - Switched-Capacitor Wide Input Range Voltage Converter

LTC1144, Switched-Capacitor Wide Input Range Voltage Converter

The LTC®1144 is a monolithic CMOS switched-capacitor voltage converter.

It performs supply voltage conversion from positive to negative from an input range of 2V to 18V, resulting in complementary output voltages of *2V to *18V.

Only two noncritical external capacitors are needed for
