General Description

The LMC7660 is a CMOS voltage converter capable of converting a positive voltage in the range of +1.5V to +10V to the corresponding negative voltage of -1.5V to -10V. The LMC7660 is a pin-for-pin replacement for the industry-standard 7660. The converter features: operation over full temperature and voltage range without need for an external diode, low quiescent current, and high power efficiency.

The LMC7660 uses its built-in oscillator to switch 4 power MOS switches and charge two inexpensive electrolytic capacitors.

Features

  • Operation over full temperature and voltage range without an external diode
  • Low supply current, 200 µA max
  • Pin-for-pin replacement for the 7660
  • Wide operating range 1.5V to 10V
  • 97% Voltage Conversion Efficiency
  • 95% Power Conversion Efficiency
  • Easy to use, only 2 external components
  • Extended temperature range
  • Narrow SO-8 Package
