GENERAL DESCRIPTION
The TC7660S is a pin-compatible upgrade to the Indus-
try standard TC7660 charge pump voltage converter. It
converts a +1.5V to +12V input to a corresponding -1.5V to
-12V output using only two low-cost capacitors, eliminating
inductors and their associated cost, size and EMI. Added
features include an extended supply range to 12V, and a
frequency boost pin for higher operating frequency, allowing
the use of smaller external capacitors.
The on-board oscillator operates at a nominal frequency
of 10kHz. Frequency is increased to 45kHz when pin 1 is
connected to V+. Operation below 10kHz (for lower supply
current applications) is possible by connecting an external
capacitor from OSC to ground (with pin 1 open).
The TC7660S is available in both 8-pin DIP and 8-pin
small outline (SOIC) packages in commercial and extended
temperature ranges.
