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.
