Product Description
Manufacturer Part Number: P-QTC7660
TC7660S charge pump voltage converter in an 8 pin DIP package. The TC7660S device is a pin-compatible replacement for the industry standard 7660 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 electromagnetic interference (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 10 kHz. Frequency is increased to 45 kHz when pin 1 is connected to V+. Operation below 10 kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground (with pin 1 open).
