Product Overview

The LTC660CS8#PBF is a monolithic CMOS switched-capacitor charge-pump Voltage Converter performs supply voltage conversion from positive to negative from an input range of 1.5 to 5.5V, resulting in complementary output voltages of -1.5 to -5.5V. It also performs a doubling at an input voltage range of 2.5 to 5.5V, resulting in a doubled output voltage of 5 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.
  • BOOST Pin (pin 1) for higher switching frequency
  • Inverting and doubling modes
  • Easy to use
  • 99% Minimum open circuit voltage conversion efficiency
  • 88% Power conversion efficiency with a 100mA load
  • Simple conversion of 5 to -5V supply
