LMC7660
Switched Capacitor Voltage Converter
General Description
The LMC7660 is a CMOS voltage converter capable of con-
verting 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
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 effi-
ciency.
The LMC7660 uses its built-in oscillator to switch 4 power
MOS switches and charge two inexpensive electrolytic ca-
pacitors.
