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, 35kHz for the
TC2683, and 125kHz for the TC2684.
Low output source impedance (typically 120Ω),
provides output current up to 10mA. The TC2682/
TC2683/TC2684 feature a 1.8V to 5.5V operating
voltage range and high efficiency, which make them an
ideal choice for a wide variety of applications requiring
a negative doubled voltage derived from a single
positive supply (for example: generation of -7.2V from
a +3.6V lithium cell or -10V generated from a +5V logic
supply).
The minimum external part count and small physical
size make this family of products useful for a wide
variety of negative bias power supply applications.
