    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 (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.

      Oscillator boost from 10kHz to 45kHz

      Converts +5V Logic Supply to ±5V System

      Efficient Voltage Conversion: 99.9%

      Excellent Power Efficiency: 98%

      Low Power Supply: 80µA @ 5VIN

      Low Cost and Easy to Use — Only Two External Capacitors Required

      Improved ESD Protection-Up to 10kV

      No External Diode Required for High Voltage Operation
