requiring a negative doubled voltage derived from a single positive supply (for example: generation of -7.2V from a +3.6.
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..
