General Description
The TC7660 is a pin-compatible replacement for the
industry
standard
7660
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 electromagnetic interference
(EMI).
The on-board oscillator operates at a nominal
frequency of 10 kHz. Operation below 10 kHz (for
lower supply current applications) is possible by
connecting an external capacitor from OSC to ground.
The TC7660 is available in 8-Pin PDIP, 8-Pin Small
Outline (SOIC) and 8-Pin CERDIP packages in
commercial and extended temperature ranges.
