Product Summary
The LTC1144CS8#TR is a monolithic CMOS switched-capacitor voltage converter. The LTC1144CS8#TR 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 the charge pump and charge reservoir functions. The applications of the LTC1144CS8#TR include Conversion of 15V to ±15V Supplies, Inexpensive Negative Supplies, Data Acquisition Systems, High Voltage Upgrade to LTC1044 or 7660, Voltage Division and Multiplications, Automotive Applications, Battery Systems with Wall Adapter/Charger.
