TC7660 : The TC7660 is a pin-compatible replacement for the Industry standard TC7660 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 TC7660 is available in both 8-pin DIP and 8-pin SOIC packages in commercial and extended temperature ranges. 2 3 4 Temperature Range 0°C to +70°C 0°C to +70°C – 40°C to +85°C – 40°C to +85°C – 40°C t.

TC7660S : The TC7660S is a pin-compatible upgrade to the Industry 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 (wi.
