GENERAL DESCRIPTION
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.

FEATURES
■ Oscillator boost from 10kHz to 45kHz
■ Converts +5V Logic Supply to ±5V System
■ Wide Input Voltage Range .................... 1.5V to 12V
■ Efficient Voltage Conversion ......................... 99.9%
■ Excellent Power Efficiency ............................... 98%
■ Low Power Supply ..............................80µA @ 5 VIN
■ Low Cost and Easy to Use
    — Only Two External Capacitors Required
■ Available in Small Outline (SOIC) Package
■ Improved ESD Protection ..................... Up to 10kV
■ No External Diode Required for High Voltage Operation
