... RC OSC OSCILLATOR 6 LV TC7660S © 2001 Microchip Technology Inc. DS21467A 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 ...
