TC2682 Inverting Charge Pump Voltage Doublers

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, 3.
