Product Overview

LTC1144 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 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. It contains an internal oscillator, divide-by- two, voltage level shifter, and four power MOSFETs. A special logic circuit will prevent the power N-channel switch substrate from turning on. Typical applications are 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.
  • A higher frequency outside the audio band can also be obtained if the boost pin is tied to V+
  • Boost pin (pin 1) for higher switching frequency, easy to use
  • Simple conversion of 15V to –15V supply
  • Low output resistance is 120 ohm maximum
  • Power efficiency is 93% at RL = 2k at 10kHz, V+ = 15V, COSC = 0pF
  • 8-lead plastic SOIC package
  • Temperature rating is –40°C to 85°C
