MC7660/D
The MC7660 is a pin–compatible replacement for the Industry
standard ICL7660 charge pump voltage converter. It converts a +1.5V
to +10V input to a corresponding –1.5V to –10V output using only two
low–cost capacitors, eliminating inductors and their associated cost,
size and EMI.
The on–board oscillator operates at a nominal frequency of 10kHz.
Operation below 10kHz (for lower supply current applications) is
possible by connecting an external capacitor from OSC to ground
(with pin 1 open).
The MC7660 is available in an 8–pin SOIC package in extended
temperature range.
