General Description
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...
