Description
General part information
LTC660 Series
The LTC660 is a monolithic CMOS switched-capacitor voltage converter. It performs supply voltage conversion from positive to negative from an input range of 1.5V to 5.5V, resulting in complementary output voltages of –1.5V to –5.5V. It also performs a doubling at an input voltage range of 2.5V to 5.5V, resulting in a doubled output voltage of 5V to 11V. Only two external capacitors are needed for the charge pump and charge reservoir functions.The converter has an internal oscillator that can be overdriven by an external clock or slowed down when connected to a capacitor. The oscillator runs at a 10kHz frequency when unloaded. A higher frequency outside the audio band can also be obtained if the BOOST pin is tied to V+.The LTC660 contains an internal oscillator, divide-by-two, voltage level shifter and four power MOSFETs.ApplicationsConversion of 5V to ±5V SuppliesInexpensive Negative SuppliesData Acquisition SystemsHigh Current Upgrade to LTC1044 or 7660
