... BOOST 7 RC OSC OSCILLATOR 6 LV TC1044S © 2001 Microchip Technology Inc. DS21348A EVALUATION AVAILABLE GENERAL DESCRIPTION The TC1044S 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, eliminat ing inductors and their associated cost, size and EMI ...
