TC2684 Overview
The TC2682/TC2683/TC2684 are CMOS charge pump converters that provide an inverted doubled output from a single positive supply. An on-board oscillator provides the clock and only three external capacitors are required for full circuit implementation. Switching frequencies are 12kHz for the TC2682, 35kHz for the TC2683, and 125kHz for the TC2684.
